Pharaoh Coupling Caps

[zerkalo]

Nah, I didn't tried the 47nf version (as suggested with the pcb and biggmuffpage's schematic), I went directly with the 470nf caps.

No problem with the high/low switch.

I compared different schematics and layouts with the one I have, can't find a difference.

The curse of the pharaoh takes its tall on me.

Then should be something wrong. Try to check the wiring of the pots, eventually faulty connections or mismatched wires. Probabyl it has nothing to do with it, but I was building a Vemuram JanRay, and I misunderstood a wire connection, so the circuit sounds, but even if all the pots worked fine the sound was puttering and compressed.

Do you suspect that with in the low resistor mode it sounds ok or weird? Did you try to low Sustain and also the volume pot of the guitar and emulate the low mode?

Else, check again the usual things: orientation of transistor and polarity capacitors (did you use the tantalum?), resistors value...
