Can I Convert a Tubescreamer to an Sonic Distortion or Super Metal

[mattpas]

I was wondering if anyone knew if you can use a BYOC Tubescreamer Overdrive PCB and make a Sonic Distortion or Super Metal out of it?

First thing you need is a tube screamer, sonic distortion, and super metal schematic.

I SERIOUSLY DOUBT IT

those are completely different effects..and if you manage to use the same PCB, the number of cutted traces, bridges and shorted traces would make an ugly frankenstein.. is a lot easier to make your on pcb for the specific pedal.

I'll add to the "doubt it" category. The SM-9 I have has two JRC chips in it. They appear to cascade. And the EQ on it is like no other 9-series overdrive/distortion EQ I've touched. I'd almost describe it as parametric.

I could post some gut shots of it. I have to fix a failing input jack on it some time soon. When I do I'll be sure to document the innards with my less than stellar photography skills.

You could do the Sonic distortion. From the input to after the first opamp stage is basically the same as a TS, component values are different but the topography is the same. After that they're completely different beasts though, but you could probably work the clipping into the original layout and then build the tone control on the back of the tone pot or on a bit of perf/vero. If the BYOC layout includes the output buffers you could tack that on after the tone and volume pots. You'd also have to deal with the spare opamp half because the Sonic only uses a single.

Having said all of that IMHO it's too much effort. It would be simpler to build it on perf or vero that bodge the layout.
If you wanted to build the Sonic on an existing layout it would be much simpler to use a RAT layout, which apart from the tonecontrol is slightly more similar. Or just buy a  GGG Sonic Distortion board.

so the sonic distortion is basically just a fancy distortion+/250/ross distortion? rylan

i had the ol' blue super metal way back when. i had to sell it when funds got tight. would love to see a DIY project for it.

  Like Doug says, not sure what a SM schematic looks like.
   Can you ?...maybe [doubtful]...but why ? at this point I suggest:
  It makes more sense to get a breadboard or just perf up a new boards for each new circuit topologies.
  You may find two schematics which share topologies [and other stuff]...in such cases, when it looks like 'just switch this and that and you're 'there'...then that's ~likely what it is.
