Adding coil splitters to a guitar with 1 volume / 1 tone pot

[Mike]

Some people use linear taper for the tone control, but it tends to bunch up all of the tone variation in the last 1/4 of rotation.

really? because I've found the opposite to be true. audio pots tend to just dump on the whole capacitor on the last 1/4 turn. and if you graph out a logarithmic curve you can see how that would make sense.

No you can't, because your ear does not respond to sound in a linear way.

I understand that. that's why we use audio taper pots for volume. but I'm telling you in my experience they do not work well for tone pots. our ears respond differently to different frequencies at different volumes. Take a look at the Fletcher-Munson equal loudness curve:


it shows at what db we perceive different frequencies to be at the same level.

http://en.wikipedia.org/wiki/Equal-loudness_contours

we hear the high frequencies that the tone pot cuts quite a bit better than the lows. if you turn down the high frequencies only incrementally (like an audio taper pot does in the first 3/4s of it's turn) you are not going to hear the adjustment because we hear those frequencies very well. you are only going to hear it when adjusted drastically (such as at the last 1/4 turn of an audio pot).

It completely depends on the type of filter you're implementing.
