well these are multilayer pcbs with microscopic tolerances, its not like = working around traces on an older analog board. next gen stuff.

If that was the case you could cut the trace and run ground insulated = wire for the connection.

Basically, your description is telling me that this thing has a = high noise floor, and the various distortion/gain stages conspire to = make that worse. Apparently, nothing can be done about this ever-present = noise, even with the gain settings toned down. >=20 > Sounds like a description of a vintage synth - especially one with = chorus (although this one doesn=E2=80=99t). >=20 > Brian >=20 >=20 >> On Oct 14, 2018, at 8:44 AM, Scott Fox <xxxxxxxxx@xxxxx.xxx> wrote: >> =E2=80=A2The architecture and number of gain stages and distortions = give the machine a fairly high signal to noise ratio.

Depending on what you're doing, = this can get pretty noticable in the synth.
