Reply To: using both GTR 4000 and H7600 together

[rptravis]

OK Marshall JMP 1 preamp effects loop send out to 7600 analog ins then the analog outs to the analog ins of the 4000 then the analog outs to the Marshall preamp effects return Midi from Marshall JMP1 preamp to 7600 midi in – Midi thru out to 4000 Midi in.  When I push the bypass button on the 7600 it mutes everything when bypass is off the light flashes between mute and bypass chopping up the audio unusable and noise floor is very high.
