Hey guys. I have decided to tackle the JCM 800 emulator project from Eric Hansens website. I have done search here and now am confused about a few things, so here goes. 1. Is the pcb layout on Hansen's site drawn by Buck Sears the correct one? I transfered it already and made the holes ready for mounting the parts when i came across this. 2. Is there a layout on how to connect the jacks and the on/off switch? I would like to make it true bypass and use a 3pdt switch if possible.

I read on Eric Hansesn's site that some mods to this pedal can be done the same as mods to a ROG Thunderchief. Does this mean that i could possibly hookup the jacks and the switch the same? Any info on this project would be great. Thanks

You can pretty much always hook up the jack and switch the same.

You should be able to figure out the wiring from this link.

Basically the only wires you will ignore are the gain pot's and the power jack's.

Sorry, I don't know anything about that PCB.

Thanks tcobretti. Maybe ill have to figure this one out all on my own. Still if anyone has any info please let me know. Thanks

What you need to do is take the schematic for the pedal and compare it to the PCB.  It's easy, just takes a little patience.  You just go component by component and make sure it's going where it needs to.  Even if the PCB is flawed I bet you could make it work if you figure out exactly what is wrong.
