This system has been a work in progress for a couple plus years atleast, between the custom pedals by Analogman, and the Van Aps first ever rackmount custom order reverb, it has been a long painful process, i have rewired everything with George L's, and still have a very slight hum.
the pedalboard was a custom made board by pedalboards.com, he did a great job following my design, however the power supply has issues, i am gong to try to repower the board using a pedal power if it can accomadate the whammy as well.
i get a lot of feedback at times from the "comprosser" pedal as well.
any advise would be appreciated, i am at the point that i would like to send the system out to a pro just to finish up, but i live in the Bahamas, so it's not such an easy thing to do.
the line up in order:
tuner
wah
muff
whammy to GCX
GCX loop
1. comprosser
2. TS808 mod
3. phaser
4. Chorus
in loop with foot control - Univibe
5. empty
6. reverb
in loop- RC booster
7. delay
8. Boost

any advise is well taken, Thanks

I have same issue, does the hum go away when you move pedals or cables away from power supply? You might have to place your power supply furthur away.

Great rig!

I had similar issues as well. To fix it I started by disconnecting everything from the GCX then plugging one pedal in at a time through the GCX to my amp. If pedal #1 worked then I'd add pedal #2. If #2 worked then I'd add the third and so on. In the end it came down to the George L cables. I love them because they look good on the board but they can create a hum if not completely connected. All of this checking takes a lot of time but worth it to get rid of the hum.


Good luck!
