I recently bought a VT Bass Deluxe to add some tonal options to my sound.
The pedal chain goes like this:
Korg Tuner --> Tech21 Red Ripper --> Jam Dynassor Compressor --> VT Bass --> FX Send --> EBS Tremolo --> TC Flashback --> TC Hall of Fame --> FX Return --> TC BG500
All the pedals are powered by a Voodoo Lab Power Pedal 2. The current draw is 100mA or less for each pedal.
The problem is that when I activate the FX Loop there is a noticeable hum coming from the speaker.
If I put the effects after the VT Bass (like this: Korg Tuner --> Tech21 Red Ripper --> Jam Dynassor Compressor --> VT Bass --> EBS Tremolo --> TC Flashback --> TC Hall of Fame --> TC BG500) the hum is gone and everything is quiet.
If I stop power supplying the pedals in the loop then everything is quiet again (the sound goes through as they are true bypass pedals).
As I would like to send my signal to the PA from the VT Bass DI, I need those modulation pedals in the FX Loop without the annoying hum.
Any suggestions on how to get rid of it? Any help would be highly appreciated.
