Hi everyone I'm looking for a new 2 band eq preamp for my mint green sub ray 4 that has a wonderful sound and it's very comfortable for me and I can play all kind of music, but since some weeks ago I get a terrible sound when I move the volume pot, especially if I want to up the volume because on instant I hear a little buzz or even the volume it gets turned off and I should move a little bit the pot to get the sound again, this happens only with the volume pot, treble and bass pots are okay, could you recommend me a preamp that works fine and better than the actually? I don't want to repair the actual preamp because I feel that the problem will going to continue, I prefer to change the preamp for a better one (seymour duncan, aguilar, etc) In fact the bass has 2 year warranty with GC
, I bought the bass on january 30
