So lately there has been a hissy noise in my setup and I think I've narrowed it down to my moog ep2. I'm using it as a mix control for an expression controlled loop pedal. Its been working fine but lately when I turn the expression pedal switch on and start moving the moog it gets hissy when all the way wet.
The loop pedal itself is dead silent when only the blend knob is blending the wet/dry mix and not the expression pedal.
When I add the moog into the "mix" the hiss is back?
