I had this harness custom-made for a specific one of my basses, but I eventually decided that that bass needed an active preamp. This is a pretty deluxe passive setup though, much more tonal flexibility than your typical V/V/T. It features:
-Volume pot with treble bleed, so you don't lose treble when rolling back the volume.
-Six position Varitone rotary switch, for a variety of high-cut and mid-scoop tones.
-Toggle switch to completely bypass the Varitone.
-Rotary pickup selector switch, selecting:
---front pup only
---rear pup only
---both, in series
---both, parallel
---both, out of phase
It's in excellent condition and sounds great. The build quality is quite nice. No soldering required! It has screw terminals for connecting your pickup wires and ground wire. I think I paid around $135 for it, so how about I ask for $75 shipped. It includes washers and nuts, but not knobs. If you need knobs, let me know as I have a variety to choose from. Say $5 extra for knobs.
Thanks!
