Modified the tone pot on my bass

[spinoza]

I've tried several configurations for the tone pot on my bass. The one that was already there was some kind of low-pass filter that didn't filter anything since I am using flat wound strings with no treble at all. Instead of cuting from high-mid to mid, I wanted it to cut from mid to low-mid.

Finally, this circuit works pretty well:



It's just a basic tone pot with 2 res between the lugs. I have no idea why, but I got the following result:

* Pot cranked all the way up: no treble
* Middle position: bass is still there, lots of treble and string noise
* All the way down: hard to describe, but lots of mid.

It's like 3 tone knobs in one: bass, treble, mid. Or a low-pass filter for the first half of the pot, then it becomes a regular tone pot.

I'm not too sure about the cap value. There was already one (not identified) used in a previous tone circuit that didn't do much. I added a 0,22uF.
