I have been using a visual sound visual volume pedal in front of my RM100. Just recently I noticed some very high frequency distortion when I have the pedal up full on the blackface module.
The pedal has some clean boost when it is at maximum though im not sure what the numbers are it seems like alot. The problem is only with the blackface module, my other ultra modules is set for midgain and the 1086 for high gain.
I am suspecting the pre amp tubes of the blackface module or could it be the input?
