Grandmother reverb distorts very easily

Post by isoparmesan » Fri Aug 28, 2020 9:40 pm

I have a grandmother, and I'm experiencing a fair bit of distortion as soon as I add reverb into the mix. I can have the reverb knob at 8 or 9 o'clock and the reverb will distort heavily.

Does anybody else experience this?

My current workaround is to run the output of the filter into the attenuator and then to the reverb in jack. with the attenuator at +1 or +2, and the reverb mix knob at 12 o'clock, I get no to minimal distortion.

hmm no I have not run into that

what level are your OSC's at, in the mixer?

try running them all at noon & see if that lightens up the signal?

OSCs are usually all the way up. Is that not optimal?

turning them down seems to help a bit, but depending on the frequency and overtones, I'm still getting some with the OSCs at 9 o'clock. that's with the reverb all the way up though.

that old Moog mixer is famous for it's distortion

there is a lot of flavour in it, if you use it more subtly. my osc's are usually between 10am and 3 o'clock

Hmm, I've never noticed anything that I'd call distortion form having them turned all the way up, with the exception of this distortion I'm hearing in in the reverb. I'll try to capture some video/audio and post it here as a sanity check.

good idea

and if you can record the dry/reverb as different signals that my help diagnose, panned hard L/R?

actually scratch that, your problem seems to stem from mixing them!
