Hi
i’ve just purchased a vintage Big Muff. It is the op-amp version with the tone bypass.
I’m pretty happy with the sound when the pedal is engaged, really smooth organic fuzz with tons of gain!
Anyway when the pedal is in bypass mode, it sucks a lot of tone (the “clean” sound is really dull) and also i can hear some fuzz-sound blending in.. is it normal with such a unit? Should i install a 3pdt switch on the unit?
Furthermore it seems that the sustain knob works only in the first half (changes after noon has little if no effect on the sound)
any hints
thanks a lot, regards
Fabrizio
The bypass is normal and tru bypassing it will fix it.
With my opamp muff the more you turn it up the less apparent the gain increase becomes due to saturation. At lower levels the difference is very noticeable. However it does have the right amount of gain for what it is. Yours may be normal I dont really know without hearing it.
just finished installing the 3pdt switch, now works fine also in bypass mode, thank you!
I tried the unit at low volume and the sustain actually works within the whole range, even if it is less effective in the second half. At high volume the sustain increase after a certain amount is hardly audible, maybe because of compression/saturation as you explained.
