I was bored and stumbled across this site http://personalpages.manchester.ac.uk/staff/rob.livesey/dumble/
Number 124 will be interesting for you builders out there I'm sure http://personalpages.manchester.ac.uk/staff/rob.livesey/dumble/Dumble%20%230124/
I was quite amused that whoever prepared the schematics had gone to great lengths to remove the blue and black gloop that had been put on to disguise the circuit. I can understand Dumble trying to protect his designs but putting that shite all over the boards makes it almost impossible someone else trying to repair an amp to do their job. It annoys the $%&# out of me when I get it in a pedal as it means I can't repair it myself. I paid for $%&#ing thing I'd like to be able to fix it if it breaks. I'm almost positive some makers put it on their stuff to stop people seeing that they've ripped it off some older design.
There's even a nice schematic there for all you amp builders out there.

Crystal lattices destroy electrons....okey dokey.

Oh, dont want to piss on anyones chips, I just have trouble believing that that guy, talking out of his arse in that vid, is anything other than overhyped by a handfull of people that like the amps to whom money is no object, and a few more that need to convince themselves as much as anyone else that their 30,000 pound amp has magical powers.

If it makes you sound like this... I'd prefer a Marshall MG15Dfx :lol: :lol:

If thats what happens when you let the electrons live then count me out - kill em all.

Fruit cake no doubt, but he's also eaten all the fruit cake by the looks of it. If it's not electrons that are flowing through the silicon in my Mac, then what is, raisins and glace cherries?

Is that guy off Play School? It sounds like some of my home recordings when playing whilst drunk.

this illustrates two rules of amp servicing:
1) don't touch the thing with both hands
2) don't talk to someone while touching the thing
only then can you get shocked and laugh about it :P

wow...a Dumble dissin'?

I've been reading Guitar Player interviews with Henry Kaiser for years and always thought he seemed quite a cool chap. But this is the first time I've ever heard him. :?
To be honest, both those video clips feel like comedy sketches....
-
I love Kaiser's face at the start of this.
He plays a bit, stops, and then the look on his face of "oh yeah... i DID just go there!" kills me every time

I've gotten into a little friendly debate on another forum about what fatso has been saying about electrickery and I'm being told that he is correct about the way that 'fragile harmonics' can't survive in crystal lattices. I need someone with brains to clear this up for me.
They've also not answered my point about electrons disappearing in a crystal lattice. Scr@ping the bottom of my brain for the remnants of any education and some of the physics that may have sunk in during my time looking after rather large computers for a physics dept. Are the only things that cancel out electrons positrons?
So anyone come to the aid of a damsel *cough* in distress. If it helps, they are yanks.

YANKS! Yanks you say!!!
MDV, we need you...

Electrons are fundamental particles. They cant be destroyed, or made to dissapear, save by meeting anit-electrons (positrons). For that you need some considerably more sophisticated tech than a transistor or two, and you'll get radiation poisoning from the gamma rays produced by the annihilations.
MDV M.Phys (hons) ;).
And somewhat out of my comfort zone, but I at least believe I know this -
On the 'fragile harmonics' - bollocks. Transistors preserve far more information than valves, with next to zero distortion of any harmonic unless they clip (which is as we all know another story). Valves compress the waveform a little even when not clipping and in fact never perfectly relay a signal.
And if 'fragile harmonics' cant be preserved in crystal lattices, then how the $%&# do little chunks of millions of transistors running to a clock that ticks a couple of billion times a second not lose data?
Hes blustering (dumble that is), likely off the top of his head with nothing more than passing familiarity with the terminology of Condensed Matter and hoping that hes well enough protected by reputation and acolytes for it to pass unnoticed, or even supported.

i wouldn't trust a fat ginger who dresses like a Rambo wannabe to be telling me ANY kind of truth.

Ta MDV, I pinched what you said almost verbatim but added my own little spicy bit made out of snide remarks. If any of you are interested it's here. http://www.jbonamassa.com/forum/viewtopic.php?pid=134935#p134935
If this pans out we could have a little fun with the colonials.

Henry Kaiser states that Derek Bailey was his hero
All makes sense now.
i can never figure out if every other Dumble amp I have ever heard actually sounds awful or whether it is just the players using them being into avant garde cr@p.
Started to feel the same about Fuchs amps too.......but again maybe it's the players

No bother chaps.
"electron flow theory in semiconductors. Are electrons flowing or are holes flowing through the conductors?"
Why does it have to be either? Its actually both. Holes are positve and electrons are negative and they're though to 'go round' in opposite directions with an applied potential difference.
These guys are talking about distortion and clipping, btw. There is some truth to the 'presevation of harmonics' while clipping - a transistor just flat lines at its peak voltage, whereas a valve can exceed its rating and retain a nice curvey, but skewed and suppressed wave. In the case that there is clipping, the valve (THERMIONIC VALVE, btfw, not 'tube'; we invented it (I think), we name it, and 'tube' can be bloody anything cylindrical, and anyway, valve is descriptive, thermionic valve doubly so) will retain some form of the information above the rated output where the transistor wont.
Its also true that valves favour even order harmonics, and to most they sound better.
A non-clipping transistor preserves all the information, or near enough, that passes through it.

He's throwing sieves at me now! All I can think of is draining pasta, oh my poor addled noggin.

What, in the name of $%&#, was that? It sounded like a 12-year-old doing a really cr@p Tom Morello impression in a guitar shop! :o
There's a fine line between experimental and plain old shite. ;-)

Robben Ford,L Carlton, Steve Trovato, D Linley-my fave Dumble tones
/I know Kaiser is an avant garde-ian,but I am calling this one a spoof-there are a bunch on youtubes these days...and it seems like I saw the original

Actually I did see someone playing some nice blues on a Dumble and Joe Bonnamassa sounds good on the Two Rock which is supposed to be Dumble-esque.
I think it is more the style that so many of the players choose to show off their chops
To be fair many of them (like Larry Carlton) are uber tasty but some of these great players seem so bored by normal playing and what most average guys hear as music that they find passion for cutting edge stuff that seems too far out there and atonal for the average listener.
I knew guys who were going to GIT in the late 80s who couldn't even listen to anything with a minor pentatonic anymore - they felt it was beneath them - they had "gotten jazz" the same way that Born again Christians have "gotten Jesus"

And I have an Egnater COD (California Over Drive) module for my Egnater rack already and it does sound v good
From Egnater website:
(http://egnater.com/images/cod.jpg)
What would you say if we told you that you could have one of the most famous boutique amplifiers in recent history- and you wouldn’t have to get in a bidding war with John Mayer to have it?
Well, welcome to the module that lives comfortably between the Dumble Overdrive Special and the Mark IIc, except with it’s own little twist. Even Marshall die-hards who don’t care for Fender amps really like this module because it cuts differently and you play differently. It feels and responds like a Marshall, but with a Fender EQ. You’ll get a module that brings out the mid range in single coils and just loves the neck pickup on a Les Paul. This module is perfect for both Robben Fordabees and Dream Theaterrites.
Match Made In Heaven: Try this with a T/D and get the backstage tour of blues-rock heaven.

well put!!

But then Bonamassa has been hear to say that the Two Rock and Carol Ann are both seriously lacking in bottom end but however blend well with his other choice of amps.
Do I think the amps are worth the money people pay for them? Who knows, I've never played one and I'm unlikely to.
Do I think there is a lot of smoke and mirrors and bollocks talked about Dumble amps? Yep, but only slightly more than there is about anything else that's rare and expensive and allegedly improves whatever your playing.
Is Dumble insane? No idea, but his legendary difficulty to deal with and reclusiveness only adds to his mythical status. I work with a couple of really cutting edge industry leading guys and they're a bit special as well. It may be that they're just operating at a higher level that us mere mortals.
