Hey Gang,
Just purchased this from a fellow TB'er last week. Installed it into my jazz and the tone possibilities are mind boggling. Easy drop-in application. No soldering required. Just attach your existing pickup wires to the convenient screw down posts and you're set. Took me about 20 minutes from start to finish (and I am not mechanically gifted!).
The controls are as follows:
Layout:
Master Volume: Push/Pull for Series/Parallel
3 way Switch for pickup selection. Bridge/Neck/Both
Master Tone: Push/Pull for varitone/varitone bypass
6 position varitone rotary knob.
Lots of tonal options in a passive package
Here's a quick description of the Varitone control:
A 6 POSITION VARITONE ROTARY SWITCH WITH DIFFERENT TONE CAPACITORS:
1 SLIGHT TREBLE CUT HI MID
2 MORE TREBLE CUT MORE MID
3 LOW MID
4 WARMER MID TONE
5 DARKER TONE (MID SCOOP)
6 DEEPER MID SCOOP TONE.
That said, it's more tone possibility than I currently need, so off she goes.
