Zvex - Distortron

Postby John Lyons » 16 Nov 2009, 16:29

(fixed thread heading name)
Has this been covered here?
I found a couple mentions and theories
in the Mastotron discussion but nothing
concrete.
The Videos sounded good, nice clean up and
string clarity.

It would be interesting to see how close it is to the Box of Rock, or it's actually something different.

Mr. ZVex himself allready told us it is the Box Of Rock minus the boost stage.
Only alteration I believe is a switch for the output cap..

I see no need in tracing. Unless it sounds totally different, I haven't listened to it. Might be a marketing trick to keep us from tracing it :horsey:

And then possibly the gain switch drops a stage?
I'd still be curious to see under the hoop just for
the sake of science.

I saw a post from ZVex on another forum where he said that the Distortron is electrically identical to the Box of Rock's "distortron" or "rock" side when the Distortron's sub switch is on '3' and the gain switch is on 'low'

Based on that I'd say that the sub switch is probably the input cap, and the gain switch probably switches an sho stage in and out (static boost) :hmmm:

Intersting option from ShortScaleMike :

"I think it's quite clear that the Distortron is just the Overdrive side of the Box Of Rock (3 cascaded SHOs and some filtering + tone control) with a three way subs switch which messes with probably the coupling caps between stage 1 and 2. I would guess the hi/low gain switch just shorts one of the SHO stage source resistors to ground."

If you notice on the BOR it actually says "Distortron Engine" (not Distortion) so it seems like a no brainer to me that it is just the distortron side of the BOR plus switches of course.

Same concept as how the mastotron is identical to the woolly mammoth except for the impedance pot and subs switch and transistor change from 2N3904 to 2N2222.

*bump*
Any updates? I'm especially interested in the 2 switches that only the Distortron has (Gain Lo/Hi and Subs 1/2/3).

Hi !
I'd like to know how to include the 2 switches (Gain Lo/Hi and Subs 1/2/3).
Maybe someone can help me with a shem ?
