I recently bought a Groove Tools 7 string, and I love it. I would like to get it outfitted with RMC synth pickups. After talking to John Turner for a length, I decided that I would like to do this as soon as possible. My questions- How much would it cost to get the system installed on my bass? How many knobs swtches would it add? Is it possible to put 3-band EQ plus the synth in the control cavity?
