Hey 2handband, absolutely
we're interested, I assume you are running the GMaj in MP2 loop?, if not, it will sound better than chaining through the GMaj to your power amp (maintains the analogue signal and mixes in the FXs) BTW I've tested this assertion and it
IS better (TC GMaj has no analogue pass through, first thing it does is A/D the signal).
MJMP can (no doubt) help more with the compressor (and there are other posts about this) and, A output issue, somethings getting hot and failing (seems to me?).
Noise gate jitter is a resistor (R611) See attached.
Noise Mod is 1 resister (R913, the main culprit) and 21 CAPs, minimum do R913 (so above R913, see attached noisemod.pdf, measure chassis/earth to test point (on photo), should be 190v or in my MP2s a it's little less (~187v), above 190v causes problems). MJMP can sell you a noise mod kit with all the right bits of the best components just PM or email him.
Also worth changing the input jack while you have it open (too easy and it takes the most wear and tare). It's a longer thread than normal jacks, again I got MJMP to send me a bunch for my MP2s, but he can tell you the switchcraft part number you need.
