    I just picked up a used John East P Retro preamp. I finished installing it in one of my P Basses, the tone controls seem to be functioning properly, however, there is a constant clicking sound.... Like a metronome at 100 bpm. It's louder in active mode, but it is audible in passive too. I already took it all apart and re-did the install... Same thing both times.

    Any idea what this is... How to fix?

    Are the cavities shielded?...if not ..try that first...Possibly try calling J-Retro about options

    Turn the ceiling fan off.

    I've had the same thing happen before and it was a grounding issue. Email John, he the best when it comes to customer service. Just keep in mind he's in the UK...time differences.

    John is GREAT to deal with regarding help with his products. I had an issue last year and he bent over backwards trying to help me. Super nice guy. Drop him an email or give him a call.

    Thanks for the responses, guys. I actually reached out to John East via his TalkBass account and he responded right away thinking it might be a battery issue. However, he then asked me to communicate with him via email which I did, but my emails keep getting returned as undeliverable. Bummer. My poor P Bass is lying dead on the bench.

    Remove your watch, keep p-ups away from the TV remote. Sounds corny but I notice it with digital electronics close to the pickups.
