clever uses for a spare potentiometer?

[willkrause]

I'm wiring up my Fender Duo-Sonic with this wiring diagram:

2S36 (2 single coil pickups, in phase/out of phase, series/parallel wiring)

http://www.geocities.jp/dgb_studio/2svari_e.htm#36

I picked up a Fender TBX unit to use as the new tone pot, and a concentric pot to use as the volume pot for each pickup, and after looking things over it looks like I will only be able to have a master volume control for the guitar because of the series/parallel wiring.

...which leaves me with a spare 500k potentiometer. Does anyone have an idea for something interesting that I could do with this unused pot?

If your other pots are 250k you can use it as a blend

EDIT: It will need to be linear taper as well

It's a stacked 500k pot (I like the treble stuff!)

It is an audio taper pot. What would happen if I tried to hook it up as a blend control? Would it be biased towards one of the pickups due to the audio taper?

An audio taper pot won't be "biased" per se, but the "middle position" where both pickups have equal volume will not be in the centre of the pot's rotation.

Also, for best results if you're using a standard pit as a blend it should have twice the resistance of your other pots, so that the way it affects the whole circuit will be the same as if you had 2 volume pots of equal value.

If you use your spare 500k, it'll be as if you'd put in two 250k volumes. It'll still work, but you lose some of that treble you love
