I was wondering.... What sorts of crazy electronics options are available out there? Basically I play with 5 knobs: master volume, 3-band eq and blend. However, I often see things like coil tap switches, and phase reversal (switch?)... Can anyone direct me towards where to learn about these things, and which basses on the market have them so I can try them out? Im not really a huge fan of fancy electronics, but Ive also not even heard of half of the things I see. Thanks in advance.
