I noticed this while I was looking at the range last week and forgot to post about it. The new EQ charts on the site are a great addition, but are they right? For example, using three similar-ish pickups in order of hotness:
Bass/Middle/Treble
Riff Raff: B5 M7 T8
VHII: B5 M6 T7
Emerald: B4 M6 T7
So the three pickups get less overall output as the DC resistance increases??? And the Emerald has the same EQ curve as a Riff Raff, but with less output???
:?
-
I am a bit confused by that, too.
As regards output, I thought that each category listing starts with the lowest output and ends with the highest output, and the given EQ curve has nothing to do with the raw output but shows only the relative outputs of bass, middle and treble. But following the forum discussions that probably will not give the entire picture since I understand that some pickups have stronger low mids (Holydiver, Crawler, Miracle Man, Warpig) whereas others are stronger in the high mids (Painkiller, Rebel Yell, Nailbomb). Add to all of that everybody hears something different as "high mids".
Cheers Stephan

Yeah, I think that's what's confusing. So a Riff Raff is similar to an Emerald, but just how much hotter is the Emerald?
It makes a comparaison across Vintage/Vintage Hot/Contemporary quite difficult...
-
yeah i always just assume that the eq charts are just for that one pickup, and aren't related to output, just the frequency curve/response. Like if a low output pickup has treble 8 and a higher output pickup has treble 6, that means the lower output pickup has more treble, not that it's hotter.
I could be wrong, though :lol:
-

I agree with the output thing
but I disagree with some of the graphics
my riff raff is no near as middy as shown on the graphics
mine has a larger magnet, which would make it more bass heavy and add some attack, but I don't think a stock raff would be that much middier, at least by listening dozens of clips for years
the nailbomb I had was also no near as middy as a holy diver or aftermath, and I had enough pickups in those guitars to have solid comparison parameters
the miracle man should definitely have more bass than the cold sweat and aftermath
my aftermath sounds hotter, thicker in the mids, less bright, but slightly less bassy than the cold sweat in the same guitar
if the eq charts can't be compared at least in voicing terms, it kinda misses the point of having those charts
-
I also doubt the accuracy of the EQ charts especially between the aftermath & the Miracle man!
However we are ALL responsible for the EQ charts in part as those values were gathered during MDV's pickup EQ thread

I haven't tried enough bkps to really judge if the EQ charts are right or not... I just meant the principle :)

Yep, that's exactly how I'd read them.
If the Riff Raff has treble of 8 and the Emerald has 7, it doesn't mean the Riff Riff has more "treble output". Just that it's brighter. The charts have nothing to do with output levels.
Or to put it another way, the EQ chart is the Tone Controls and the output is the Volume!
-
So looking at the charts, a Riff Raff has a single bar more treble, mid and bass than an Emerald?
The curve for both is the same, i.e. bass = x, mid = x+1, treble = x+1+1.
What exactly does that translate to then? I don't get it! :?
-
Hang on, does it mean if a Riff Raff is "like" Vol=8 and Tone=10 then an Emerald is that Riff Raff with Vol=10 and Tone=8????
-
actually a 3 band "tonestack", not just a "tone" control
-
But then again, surely if you lower all the EQ bands by the same amount then you're reducing overall output?
I'm completely lost now.
-
yeah i think you're overcomplicating things there dave (coming from me that might be a bit hypocritical, lol, as i do that all the time).
keep the ideas of output separate from the eq chart.
Look at the eq chart and that tells you a rough guide of the pickup's eq. A higher number means more- so a pickup with treble at 8 is brighter than a pickup with treble at 6.
Then look at the output to see how hot it is.
I kinda know what you're doing with all those xes, that if the pickup's eq curve is only relative to itself, that a curve of x, x+1 and x+2 is the same whether you make x be 3 or 7 (unless you start working it out as percentages, in which case it might be different).
But yeah.
Now you have me not knowing which way's up. Thanks :lol:
EDIT: to your edit: me too :lol: :oops:
EDIT #2: how about this.
The eq is unrelated to output. it says nothing about the pickup's output relative to other pickups- but it does say something about the pickup's EQ/frequency response compared to the other pickups. It's the ratio of bass to mids to treble, but it also gives a general idea of how bassy/middly/trebly it is compared to the other pickups in the lineup.
For example a pickup with treble of 8 will be bright, and that can be compared to the other pickups.
So, for example, using your x, x+1 and x+2 example, a pickup with BMT of 5, 6, 7 will have a similar ratio of bass to mids to treble as a pickup with a BMT of 7, 8, 9 (assuming it's not done by percentages), however, the 7,8,9 pickup will be a bit brighter.
That's my story and I'm sticking to it.
-
three rules to choose a pickup :
listen to tim
if youre not satisfied with the answer ask Eric (:D), if you seek tightness only ask MDV ;).
More seriously those charts could be the result of gathering infos about how users feel their pickups response on their axe so its biased by the guitars/amps' people are using or it could have been done based on the guitar they used to do the samples for the website. Anyways it won't match the result on your own guitars. You will really be able to tell when they're soldered and when you made it scream through your amp'.
I know a lot of people use those charts but in BKP case the boards are such a nice place to come and ask, its rare no one who knows the BKP range does not take the time to reply and explain to you what pickups could match your tonal needs.
Just saying in the end people, amps, guitar and even pickups are unique so you can't expect eq charts to be that accurate, just gives a partial idea on how it could sound.
-
Ok, so we're getting somewhere :lol:
So the Emeralds I have coming in the next few days have the same EQ curve as a Riff Raff. But as they're hotter, there's a reduction in treble which also has a compensated reduction in mids and bass to balance it.
So by the sound of it, Emeralds are Riff Raffs with a bit more beef and bit less spike.
That is, unless I've done a dave_mc and completely over-analysed it :lol:

You have TOTALLY over-analysed it, to death! :P
(Uncharacteristically so, I must say)
But I think your final analysis makes sense!

i haven't tried the riff-raffs or emeralds. But assuming what we're both saying is right, then that sounds about right, yeah.

Hmmm
Its not an unfair point. I had noticed this, and had noticed that the vast majority of the estimates were over 5, and it seemed that if some part of the spectrum was suppressed to someones ears then they were reluctant to give an estimate for it less than 4.
On the other hand, it seems that the readings *should* fall round 5, that being assumed a 'neutral' value, no more or less than what one expects from years of playing hundreds of different guitars and pickups, but the tendency was toward 'MOAR'; choosing higher numbers as a 'hype' sort of a thing.
I considered, briefly, normalising all the data round 5: i.e. taking the average of the EQs, fixing that at 5 for every pickup, and then reducing (as would be the case for all of the data I got) the values so that they sat around that line. In that case, where you have pickups that have, say 5,6,7 and 6,7,8 they would be the same (4,5,6)
I didnt because I couldnt really; that wouldnt have been an honest thing to do with the data, based on the premise of the data gathering and the method by which the final readings are compiled, which depended entirely on lots of subjective, knee jerk responses giving something thats representative of the performance of the pickup that *most* people can expect.
Also, if its the natural inclination of the user group to give higher values then I couldnt distort the expectations of BK neophytes by artificially dropping the values, even keeping the same differences between them.
I think in those cases some odd and ephemaral psychoacoustic phenomena may have come into play of the pickup has a similar balance but sounds less aggressive, smoother, not so compressed, more compressed, whatever. Or it could easily just be that there wasnt enough data to iron that sort of oddness out of the final sets.
I wouldnt try to think about them as 100% objective numbers. Its not like anything was measured for it.
As far as specific user experiences disagreeing with the data goes....sucks for you :lol: I kid; its simply that the values you see are 'democratic', for the most part; there was quite a bit of variation between estimates in the final groups (eric, you dont agree? Tough; your values are in the data that was used for the charts on the site! As are mine, but I didnt give anyone a stronger weigthing in the stats) and the values you see are an average of lots of users; thats sort of the point.
It all hinges round how the data was gathered.
Except single coils and any necks that theres achart for - I beileve a similar sort of thing was done @BK, after Tim and I went through tims own subjective estimates and my(/your) data and they were in excellent agreement, Tim was happy that estimates done with fewer people in-house for the pickups that no data was available for would be consistent with the estimates done by us users.
-
That doesn't help me one bit MDV :lol:
So basically, the charts are specific to each pickup and can't be compared? In which case they're of no use for comparisons?
-
Well, ish, and no - the charts were made by, in part, an average of the estimates given by all users that chose to give the estimates for them (so since no one has all the pickups except tim and maybe philking, who didnt choose to take part) there is isolation between the pickups because they depended on what any given person heard and submitted.
The other part was a small adjustment from tims own estimates, which were all very close to the statistical ones. The final values were an average of the data from the survey and of tims.
On the whole for interpretation of them, the difference between the bass mid treble for each pickup is much, much more usefull than the actual value (which is meaningless in an absolute sense anyway; what the hell is "7" of "Bass")
-
OK, so the curve of B-M-T is fine and a representation of the product. I get that.
But back to my core question, how does the EQ chart for a Riff Raff and an Emerald give any info as to the difference between them?
Sorry to keep harping on about this but if the information is there to help people choose which pickup suits them best, they need to know how to interpret the data. The clips are useful, but we don't know what guitar or amp was used. Or what the volume/tone control settings were. Or what (if any) post production was done etc.
-
As I understand it there was no post production.
Bear in mind that the actual response of any pickup is far more complex than 'bass mid treble'. Its a really clumsy way of doing it; its just familiar and comprehensible to most people. There are differences in voicing, both in EQ if you use greater resolution than just 3 bands, and espacially the envelope of a note/chord that a pickup will create (in interaction with a given guitar or player) that cant be represented like that. The BMT values are 'about right', but they arent enough, imo; I'd like to see fourier transforms of the responses, but thats probably just me :lol:
Same as, say, a dual rec and an uberschall with the eq all set to 5 have a similar sort of balance between lows mids and highs, but they sound totally different.
-
The B-M-T definitions seem to work OK for DiMarzio and Seymour Duncan though, and you kinda know what you're getting?
-
Yeah, thats the idea; to give you more of an idea what to expect. Its not a set in stone measurement, including for dimarzio and duncan. Its a rough indicator, but its to be taken with the products description and specs as well.
-
I wish the EQ's were listed as Bass, Low Mid, High Mid, High.
-
djpatb - that would be helpful
MDV - SD and DiMarzio use numbers to help compare pups though...
-

That's basically how I see it as well. The EQ curve is helpful if I have a particular BKP model in one guitar and need something more/less in a particular area, then I have a reference point to find something better suited for a particular application.
-
Well, ish, and no - the charts were made by, in part, an average of the estimates given by all users that chose to give the estimates for them (so since no one has all the pickups except tim and maybe philking, who didnt choose to take part)
I didn't take part because I can take a pickup and put it in several different guitars and get a different response, so to compare one pickup with another, you'd have to have all humbuckers in the the same guitar, all strats in the same, etc.
Even then, to do it properly, you'd have to play the same piece with the same attack, for each pickup and record it to allow your ears to remember the sound.
A great example of how playing affects the sound is Tim. If you have ever heard Tim play, he gets some amazing sounds out of the pickups. However he still sounds like Tim, and his overall tone still sounds like Tim. The sounds that I am looking for in a pickup revolve around blues and classic rock. I can get those sounds out of a Miracle Man and Warpig (all be it heavier sounding), or a Stormy Monday or Mule. The amp I am using can also make a big difference, as does the setting. Irish Tours and Riff Raffs can sound very bright through the wrong amp settings at a lower volume, but put them in a band situation and they are great.
One other thing that I don't think is on the new site even, is the different magnets. I have Stormy Mondays with AII & AIV magnets, and Mules with AII, AIII, AIV & AV. This makes a big difference to the tone. Also, and this might be Dave's point, how do you express drive in these charts? By playing harder, and using 11-50 strings, I can get a Stormy Monday to drive my amp into feedback. I can get this same drive from an Emerald or Abraxas without playing as hard, but there isn't anything that show's that. DC resistance isn't what matters, it is the output of the pickup into your amp. Heavy gauge strings hit hard give more output than light gauge strings just being tickled.
So all things being equal, the sound examples will probably give you the best idea of the tone. The EQ charts are at best just a subjective indication of what the pickup will sound like.

So all things being equal, the sound examples will probably give you the best idea of the tone. The EQ charts are at best just a subjective indication of what the pickup will sound like.
Then you sorta missed the point of how I did it mate - the entire idea was to USE the fact that every pickup will sound different in lots of guitar and with different players and through different amps and so on and so forth, get as many estimates from as many people, and therefore guitars and setups as possible, and take an average of all of them to get the most representative guess, or most usefull one for any given prospective user, at how the pickup alone is infuencing the sound, because all those differences would elimiate - there would be as many people using them in bright guitars as dark, for example, and the estimates would fall on a gausian distribution (and they did fall on a gausian), showing that these variations are stochastic and would cancel.
Myself and tim are both aware of the difficulties in subjective, or isolated estimates that you mention - the entire thing was designed precisely to use them in a fashion that in the final analysis would circumvent them.
-
djpatb - that would be helpful
MDV - SD and DiMarzio use numbers to help compare pups though...
They will have been made by a couple of people, however, and the values chosen to be different, They probably ran into the same sort of thing and intentionally made the values vary between pickups more, whereas our method had far more people involved that werent (in theory: it would have ruined it anyway) choosing values based on the other values they'd chosen. Its just a consequence of the methodology.

edit: grumpiness removed
Phil - I'm with you 100%. Even the tone clips are limited in their use as the guitar/amp/cab/speakers aren't mentioned anywhere.
-
And I dont really care that youre confused; I've tried to answer your questions but the fact is that part and parcel of the method used being to make it as representative as possible for as many people as possible, It was never going to work for everyone.
Plus they're there to be used in conjunction with all the other information available (inculding calling and asking, posting on here, user clips etc etc).
The method is better, however, than a couple of people stitting and making them up, because while they might look more consistent from pickup to pickup that brings in all the problems that phil raises that I tried to get around; but the numbers are still taken as gospel, as though they're empirical measurements, by majority of customers, which they arent, which is why they were never on the site for so long. So, more confusing or more misleading? Eeenee meenee mineee...
-
fwiw the original data, before averaged with tims estimates, has the riff raff at 5-8-7 (rounded up) and the emerald was the only bridge HB I didnt get any estimates for, so that was BK in-house estimate, not from the survey.
Edit - no, the reble yell is 587, the riff raff is 577. VHII is 467
Much of the difference will simply be from rounding
-
The B-M-T definitions seem to work OK for DiMarzio and Seymour Duncan though, and you kinda know what you're getting?
Sort of.... but isn't that largely based on you, the customer, knowing a couple of the pickups from personal experience, then using that knowledge plus the tone charts to make new choices? I don't think anybody's tone charts really work as stand-alone tools. And (unless I'm missing something here) I don't think DiMarzio and Duncan's numbers give much indication of relative performance and output, any more than the BKP ones do. They're still just giving an indication of the EQ for that particular pickup.
(Incidentally, for the models I've tried, the numbers in the DiMarzio tone charts always seem about right to me, but the Duncan ones seem way off. I guess it depends what they're taking as the "average" or start point.)
Gotta say, I'm a bit baffled by this thread. OK, so the clips and tone charts don't work for everyone. But loads of people were asking for them, for years. Now we've got them, and suddenly we're piping up with the "what guitar was it, what amp was it, how was it recorded, apples and oranges..." stuff again. Surely we've been through all that enough times? If they don't work for you, you don't have to use them. We managed without them before! :P
-
I guess I was trying to find out if the BKP ones could be improved in some way to make them more useful. I was hoping the new site would be an improvement, but to me I don't think it is.
edit: grumpiness removed
-
I can now see why Tim was originally not up for EQ charts.
This just goes to prive that people will never be happy no matter what is handed to them.
Even if they asked for it they still want more!
And also just to clear it up i arent having a go at anyone then just stating what i've gathered from this thread.
-
Sorry to bring this up again, but I don't think that point was addressed in the discussion:are the EQ ratings for the pickups as a set or mainly for the bridge pickups?
Thanks, Stephan

Bridge. I think!
