this amp has been sitting in a closet for the last couple years. I can't really play it anymore because I can only use it at "thin-walled-apartment/cranky-neighbor-next-door-with-new-born-infant" volume levels. plus, my playing is so abysmal, I wouldn't want anybody else hearing it anyway.
I sent it to Monsta-Tone when it's first round of "issues" flared up a few years ago. I think some LDRs weren't functioning properly, along with some other fried doo-dads, and worn out this's-and-that's.
Now on to the current problem
the MIDDLE tone knob is giving me problems, and here are the symptoms:
in the clean channel with the "Gain" knob on a higher setting (approximately 6/10 and higher), and the Master volume set to 2/10 (cuz I can't turn up much louder than that) the "middle" tone knob (with the treble, and bass knobs set to lower settings so the **** thing actually has an effect) works as it should up until the 6/10 mark. then turning the Middle knob higher than 6/10 the sound from the speaker starts to fizzle, crackle, fart, sputter, spit and piss. sort of like there's dirt in the contacts inside the pot. but I don't think its dirty contacts, because this fizzling continues even when not turning the knob. and the sound also cleans up when I turn the gain lower. I think also that this issue changes/improves when the Master knob is turned up. but I really can't tell because I can't turn the amp up too loud.
HOWEVER, this issue completely clears up if I turn the Reverb knob up to 8/10 and above. but I get no reverb effect at all out of this amp.
also, this problem clears up if I turn up the Treble knob up past 6/10. but I think this is only because turning up the treble turns off the Mid knob function entirely
the G-EQ, and the Presence knob have no effect at all on this problem. and this issue doesn't seem to persist in the Gain chanel
I tried the pencil tap test on all the tubes and they seem ok
I might try to make a video
