It’s An Addiction, I’m Sure!

At work right now, but would a wrong-value pot, or one with the wrong taper do it?  Even maxed out, it doesn’t clip my Two-Notes, but the other two will.  I’ll hit the pot and switch with contact cleaner when I get home.

MarshallJMP:
No normally not but check the value to make sure. The taper doesn't matter, it will just give a different feel to it but at max it should be the same.

Moff40:
I was thinking that wide open shouldn’t matter; it should present no resistance.  I’ll check with a meter, and also check to see if an additional or higher-value resistor has been added.

Moff40:
OK.  I hit both the switch and the Ouput Level pot with some contact cleaner, flicked the switch and twisted the knob back and forth multiple times, and no change.  From the markings, the pot is an A50K rather than B50K, so audio rather than linear taper, and measures ~48K front and back fully off, and 1 or two ohms wide open.  Seems within spec.

Is there anyplace where a resistor could have been added or bumped up?

MarshallJMP:
Have you tried the send output, is there a difference?
