Hi everybody. After a Bongo-induced hiatus, today I picked up my Carvin BB75 again. I wanted to record some sound clips by plugging it into my SB Audigy 2, and as soon as I connected it, I noticed a ground noise that I know it was present from some time but didn't pay attention to it until now, so used to the quietness of the Bongo. The weird thing to me is that it changes (seems louder) when I emphasize the neck pickup with the blend knob. Also changes if the position of the instrument changes (i.e. I turn with the bass on). I also noticed that the volume knob is scratchy and that the noise gets louder with full volume (not because of the full volume. It changes drastically by just turning the volume knob a little bit from full blast). I've uploaded a sound clip for you to have a better idea of the problem. You can hear the changes because I either turned the blend knob or moved with my bass on. It sounds pretty loud, but that's because I amplified the noise with my recording software. I appreciate your input on this, specially because I don't know a qualified guitar electronics' technician here, but maybe if I know what's causing the problem and let it know to a good tech, he/she may be able to solve it.
