On Board Preamp for my Peavey tl6
So i just received my Peavey TL6 that i bought from a fellow talkbasser, i like how the preamp sounded, but the knobs on that is kinds loose, there is no center detent on that. Can i just replace the knobs on the bass? If it is not possible, is there any preamp with the specification as the peavey tl6?
bass 50hz, high 2khz, mid shift 125hz to 2khz, blend and volume.
