I use a Gator G Bus to run my board. I just tried a dedicated 9v supply with the same result.
To clarify, I get hiss at every position of the frequency knob, but the pitch changes low to high as I turn it clockwise. It may not get louder, but it seems louder with the higher pitch.
If I turn the volume down on my guitar the hiss seems overwhelming. If I turn the guitar up, the hiss is still there but only noticeable when I stop playing - it kind of resembles single coil hiss in that regard. However, it is loud enough when not playing to make me not want to keep the pedal engaged. BTW I have been doing most of the testing on my strat, but I also tested it on an Ibanez with 2 HBs with the same result.
