At the moment this is the system:
My own homemade isolated power supply. In other words a multi socket extension lead with multiple power supplies! Big, ugly, easy to fix totally noise free.
Effects loop send or bass > Zoom MS-60B. This is my HPF, compressor and tuner. I use both outputs. Output 1 goes into Sweet Baby low gain distortion which colours the sound when I'm not using a valve amp. Not much but just roughs up the edges.
Sweet Baby > Tri Parallel Mixer (TPM) main input.
Zoom MS-60B 2nd output > Joyo XVI octave pedal > Big Muff distortion > Mooer Pitch Shift (used as a chorus). This chain into channel 1 of the TPM.
Source Audio Soundblox Bass Envelope > channel 2 TPM
EHX Mini Tron > channel 3 TPM
TPM main output > amp
The Zoom and Sweet Baby always on.
The short chain can be all on / all off using the TPM, or used individually as needed. Usually 1 octave up with some distortion kind of mixed into the background when the other guy takes a solo.
The two envelopes is a bit of an experiment. I'm not keen on an envelope taking over the whole sound so the TPM allows me to keep my clean signal and blend them to my taste. Having both isolated in their own loops on the TPM means neither is affected by any other pedals and opens the door to some interesting double envelope sounds. I may decide in time this is ott and ditch the Tron but right now I am enjoying myself.
When I do a quick set up/pack down gig I take either the Valeton Dapper or Zoom B1-Four. The B1-Four set up as individual stomps not as patches: HPF, Distortion, Chorus, Octave, Tron. This gives me similar to my main board in a small battery powered package.
