I am putting together a Frankenbass that will have P and MM pickup configuration. I want to have it wired with a volume control for the P, and a 3 way switch and volume control for the MM. No tone controls at all. Is all the hardware I need: 2 volume pots, a 3 way switch, output jack, and 2 knobs? Will I need capacitators even though I have no tone controls? Thanks in advance for any replies.
