[quote name='spellonyou' timestamp='1340988303' post='1712564'] Threading the lead between powerplant and pitchblack through a ferrite bead made this problem disappear completely. As far as the actual cause of the problem is concerned, and how exactly the noise travels from the pb to the deepressor is a mystery to me, but there you have it. [/quote] Well, as it turned out during yesterdays gig, the problem hadn't been solved after all, and I am still looking for tips on what to try next ... Edit: running the compressor on a battery cell also seems to make the noise disappear but as the pedal is normally fixed to the board with 4 screws making battery changes quite a hassle that's only really a last resort option...

Hi, I am experiencing a problem with hum in the following setup: signal chain: (any bass, or only a patch cable); korg pitchblack; palmer deepressor; behringer bdi21; amp (any kind) all powered by Harley Benton pp junior, with the pitchblack using a battery cell as alternative (makes no difference) the hum is only present with the tuner and compressor switched on simultaneously. its pitch and loudness seem to be stable. touching the casing of the compressor with bare skin, providing ground, will eliminate the hum. engaging the input attenuator on the compressor also makes the hum disappear, or so it seems. nothing else makes the hum disappear, apart from switching off the tuner. I did not however try to add electrostatic shielding around any of the pedals nor powerplant. i would like to keep the attenuator disengaged and not to use a battery cell as power supply for the deepressor. gigging with bare feet is also not an option. what could / should I try next to find a solution ?

My name is Sandor, I come from the Netherlands and I"m a recreational player in two bands with occasional informal/amateur gigs. My main bass is a Cort 5 string, I use school equipment in one band and a semi half-stack that I own in the other. I am also working on a pedal board which currently consist of a compressor, di-box and tuner, running from a small power plant. I enjoy reading these forums but only really registered to ask a question in the technical section, to be honest. I hope that that's okay and will not be found offensive. Cheers!
