Kustom K100-2 reverb problem

[gui_tarzan]

The reverb on this head sounds good when it's all the way down, then as you turn it up the volume drops and it gets swampy - real bad. I've swapped out some of the e-caps in that section because the sound was fading after 15-20 seconds, and it doesn't seem to be doing that now but it's unusable (and was before the cap swap) if you turn it up at all.

Try disconnecting the reverb pan output.

If the problem stops, the issue is in the output circuit.

I don't have that schematic but there is a piece of it here (http://vintageamps.free.fr/K100-2mod.jpg) which shows the output stage voltages.
