Looking for solutions to getting my stage sound up without the feedback. The Tonebone PZ-Pre seems to have the trifecta of feedback suppression: phase reversal, hi-pass filter, and notch filter. Just wondering if anyone uses it on stage, and if it helps. Thanks! --Jim from Moose Jaw P.s. If it helps I currently use the K&K RAB p/u and preamp, through a _______ head and Eden 212 cab. I also use the Tech 21 Sansamp Bass Driver deluxe. (I'm in between heads, but am ordering the Aguilar Tonehammer 500). My bass is just a cheap blonde double bass from Long & McQuade.
