I know I’ve seen this topic on here before. I switch between two basses live and there is a large difference between the output level, so I have to adjust it on my preamp pedal every time I switch. The louder bass has individual volume knobs for each pickup, so I can’t just roll those back to make it closer to my p-bass, as I adjust them often for different tones, it would get confusing. Looking for a pedal solution. Anyone?
