OK, I have some pending (easy) improvements to the meters, then I'l get onto this. > i put in a music-dsp shaper (archive credits patrice tarrabia > and bram) after the inverter, and with some eq (hp basically) > before entering the first valve, it sounds surprisingly good. > especially with the bridge pickup, the neck pickup is still a > bit muddy. OK, time for a quick lesson - whats the difference between the pickups? My bass (cheapish active 4 string) has two sets, a single wide one and a pair slightly offset (they say duncan on them FWIW). There is a knob that, I think crossfades between them. > >It doesn't. there are no time domain effects, and it doesn't adapt to > >amplitude - just a static trasfer function.

I think it is more like a slow acting saturation. My Valve rectifier plugin (valve_rect) was an attempt to capture that, but I expect it needs adjusting, or rewriting. - Steve
