Hello,

I've just "finished" my build of the Black Arts Revelation Super Bass Debugging clone based on this layout :

http://tagboardeffects.blogspot.fr/2017 ... super.html

And 2 strange things occur :

1) Potentiometer seems to have effect only on the last quarter.

I've checked values and i have the same as the layout indicate (100k A x2, 500k A)

2) when i turn the effect on, the “gain” is not immediately as the good value, i can here like a “swelling gain”.

After ~1sec it’s ok.


Just for information I have not found an y 6k resistor so I replaced them by 6k2.

Thank you for your help
Thomas

I don't see a schematic. I must be missing something. Hard to say without one.

Sorry to resurrect an old thread. I just stumbled on it,
I happened to have a Revelation Superbass and I traced it back then.

It's based on a stripped Big Muff,
