Title: Boss OD-1

I doubt its worth the £100+ these go for on the bay, but I must admit I'm quite curious. Not many pedals advertise themselves as an OD-1 clone. Anyone with any experience?

Doing some digging. Theres two version apparently - naturally the first one is rarer, more valuable and sounding better ;)

Is that the right clip gwEm?
Really only showed off his Marshall amp  - couldn't se any discussion of the pedal

I rather liked the solo tone on this clip

Same again - more gain

Pedal apparently based on a OD1 without the buffer (hardwire bypass instead) but quite expensive
Tasty playing too!

Are you researching Jake's gear gwEm?
I think with a few tweaks of the RC booster you could get quite close (would probably feel a bit more hifi)

Have I missed something ?
That was like a huge leap there Will.....unless I missed a clue

EDIT: Ah - just looked at what are we listening to......makes a bit more sense now

You got me Will ;)

Feline: it seems like you noticed, but the clip I posted was boosted with an OD-1

HTH seems an OD-1 fan from some forum searches, perhaps he'll join us in a moment :)

I like different pedals on my Marshall, but none really get that hair tone.. GE-7, crunchbox and phil hilbourne treble booster are my favourites on my 2204. GE-7 comes the closest, and my SD-1 before I modded it.

the OD-1 is great at boosting a Marshall, I've modded an SD-1 to OD-1 specs and really should get on the case of offering this up at some point.  I might end up writing up a 'how to' and selling the mod as a kit.

The dude who recorded our EP had an OD1, sounded awesome through a ceriatone 2204 clone and EV12L speakers. We ended up doing both rhythm tracks with it just using different guitars.

for some 80s metal style clips, a coupla our tracks using it are up at www.myspace.com/gaywyre (http://www.myspace.com/gaywyre)
leads were done through a 5150

Im quite surporsed boss doesnt still make them, they seem to go for quite big money on ebay.

Just compared the SD-1 and OD-1 schematics. The dual op-amp version of the OD-1 is very similar to the SD-1 indeed.

what's the difference between them? isn't the OD1 basically an asymmetric tubescreamer? I might be thinking of something else

both the SD-1 and OD-1 could be described a asymmetric tube screamers. Obviously the OD-1 has no tone control. There are some differences in component values, and the second gain stage is configured as inverting rather than non-inverting.

if you're feeling cheap-arse, you can buy a single resistor and a capacitor and move some components and wires around to perform the conversion.

edit: obviously, while you're in there, you might want to perform other mods

on Friday ran out at lunchtime to buy a new SD-1, on my way home brought the components for the mods to OD-1 specs.

few hours ago I tried the stock SD-1.. i still quite like the SD-1 in standard spec, even if its a bit meh.

so just finished modded it to the later dual opamp OD-1 specs. sounds really really good. colours the sound hugely - very bright. changing the EQs on my 2204 to suit, the most amazing 80s metal tone comes out. cleans up well too.

found some circuit tweaks on the net to make it closer to the original quad op-amp version, which I'll now try. will report back

the brightness is alot more manageable with the capacitor changes to bring it closer to the quad version specs. The pedal is a bit less fun though.

i'm never sure if changing audio path electrolytics is a good mod. anyway, i changed them out... could this be the source of the reduced fun?

First thing that came to mind was Ibanez's "hand wired" tubescreamer that chalks in at $300

errrr...correction; $350  :?

Sounds like I may have to keep my eye out for one of these... bright... 80s... cleans up well... where's the downside?! :)

the downside is the price IF you can find one.

its really not difficult to mod a SD-1 to OD-1 specs if you can read a schematic.  if not, there are people who will do it for you.

a nice tweak might be to hardwire a true bypass and take the input and output buffers out.  my experiments show that the buffers do thin the tone slightly.

Looking at the schem for the OD1, it's pretty simple, so I think i'm gonna have a go at building a clone, with a couple of little tweaks... removing the buffers sounds like an interesting idea!

Has been ages since i've faffed about with pedals, been working too much inside mixing console channel strips!

an od-1 would be really nice with your plexi-modded laney oli!

some people on the net claim the OD-1 was release before the tube screamer. no idea if this is true, the od-1 was released in 1977, and i think the TS was as well, but I've found no actual evidence.
Title: Re: Boss OD-1
Post by: HTH AMPS on November 29, 2009, 04:46:36 PM
the earliest reference I can find to a TS-9 or TS-808 is 1980, with the suggestion that a few of them were shipped to non-US destinations in 1979, but that these models did not have the classic tube screamer circuit.  I found this info on the Analogman website.  This website also says, on their OD-1 page that, the OD-1 was the first tube screamer 'type' overdrive on the market.  It would therefore appear that the OD-1 precedes the TS-808.

btw, I've recorded a clip of my SD-1 to OD-1 mod and its uploding onto youtube now - check later if you want to hear it.

what about those orange ibanez overdrives that were pre ts?
or were they a totally different circuit again? i just thought they were the predecessor to the tubescreamer range. never been near an actual one so no idea, saw one for sale a while ago, it wasnt working and it still cost more than my 120w tubehead (it was a bargain of a head)

they were a different circuit design and sounded more fuzz-like.

Sorry for the thread revive, just seen both an od1 (2nd series i think, so dual op amp) and a fulltone ocd on our local auction site. I've heard a bit of buzz about the ocd on here, but never really paid attention, are these better for overdriving dirty amps or as flat out distortion pedals?
any one with experience with both? looking for basically an 80s traditional/thrash metal tone.
id be using them to crank the front end of a 800 style amp

The OCD is definitly an overdrive, not a disto. I never tried the OD1, but from the name and what have been said in this thread, it's obviously an OD too.

you can use it as a light distortion, but its better with an already crunchy amp. the od-1 is perfect with a jcm800, but its no transparent drive, its very coloured. its ideal for the traditional 80s tone, but no one could say this is a boutique effect.

od1 auction ended and i got a very reasonable fixed price offer so grabbed it
we used one through a ceriatone 800 for our recent recording and it sounded awesome. was before i had my red bear so hopefully sounds just as good (or better)
i think the one we used looks like the same later model as i just bought.
will put the ocd back outta my mind for now. dont need a 6th od/dist pedal
probably should start selling some of the others

if you want to hear an OD-1 into a JCM800, look no further... http://www.youtube.com/watch?v=UFqQZjJ828c

the amp is modded to have more gain already, but I'm only running the amp's gain on 6 in this clip and the OD-1's gain around 1/4 up.
