I’d check your signal and power supply cables for solid connections and ground issues. That description sounds like you have a bad cable or a bad ground somewhere.Long-time reader, first-time poster here with a question for the community: How noisy are your Benson Preamp pedals? I just got one, in part after reading all the positive reports about them in this forum, but when switched on there is a scratching/bubbling/boiling sound that increases as I turn the volume knob up. The noise is always present, appearing even when there is no input signal going into the pedal. This doesn't seem right to me, especially since I get no strange noises using the same setup with my Greer Lightspeed pedal. So did I get a defective pedal, or are the Benson Preamps really noisy? I am assuming the former, given that none of the reviews I have read (or demos I have heard) talk about an unusual background noise, but I would love to hear from other Benson Preamp owners about this. Thanks!
My Preamp isn’t noisy.
