I haven’t tried it with the exh power supply just my voodoo lab. I tried it first in line and tried it after my soulfood which is almost always on and there seemed to be a lot of volume loss after the soulfood. So I moved it in front of the soulfood but after my compressor and I seem to get the best tone out of it there in my setup.
Use voodoo lab pp2. I now have it 2nd after compressor.
