Ibanez 7TH Heaven schematic

[Mihkel]

Sorry for the dumb schematic- plea, but I have a 7TH Heaven distortion pedal that I'm trying to turn into a Marshall Shredmaster. The problem is that the switching circuit has me stumped. I've compared the switching to the original Tube Screamer switching, but they don't appear to be exactly the same. If anyone could share a schematic for this pedal, I would greatly appreciate it.

Thanks

I posted a similar request about a year or two ago, got no help.

Hope you're a bit luckier.
