MXR Wylde?

[Marcos - Munky]

Yeah, I saw this article. And I believe that is a modded SD-1, because he used a SD-1 before he changed to the MXR one.

I would trace it out...but half of the caps arent labled..and the print is so small on most of the other stuff i can't read it(damn surface mount :x  ).  It is definitely a SD-1 clone though.  Has an input and output buffer...though I suspect the switching mechanism is before the buffer, where on a SD-1 it is after.
The tone control is really smooth on it...where i find Tube Screamers seem to "jump" quite a bit on the last 1/10 of the rotation, this doesn't. Any guesses what kind of taper a "w" is?

Sound wise, I like it better then a stock SD-1. But i have a TS-7 which i installed a TI 4558 and assymetrical clipping, and i find it much better.  
As always..HTH, YMMV, yadda yadda yadda.

I snapped a bunch of pics with my shitty webcam if anybody wants to host them and put them up for people to see

DANG SMD's!!!

:evil:

Send them to my e-mail.

I got one yesterday and it is most definitely a SD-1 clone.. asymmetrical clipping, Yes the bypass is before the buffer (has around 1 Mohm impedance), It has no output buffer, 1 M ohm drive pot, changes in cap (well it sounds that way) and some resistors values...

Can you post that values when you have it??? please please please!!!!!

:shock:  :shock:  jajajajaja

Wylde guess......

I'm gonna say it's essentially a Dist+ with the following:

1) The .047uf cap to ground that is in series with the gain pot is probably much bigger.  Several people have posted recently about lacking bass in their Dist+ and upping that cap is the answer.  A stock Dist+ loses bass as you turn up the gain.  Upping the cap to .33uf or more retains that bottom.

2) A 2+1 silicon diode complement where the pair of 1N270's would be in a stock unit.  This gets you more output (see below) and a little more dynamics when you need it.

3) A tone circuit (well, duh)

4) A gain recovery stage to compensate for the tone control passive loss and the ceiling imposed by the diodes.
