Title: Tone/bass-cut schematic
Post by: Bash on April 25, 2021, 02:13:00 pm

For everyone that is interested, I came up with a simple way of using a blend pot to have both the regular "Tone" function and a bass cut with a single knob.

You must use a MN blend pot, so both a completely bypassed in the middle position.
Unfortunately these seem to always have a linear taper, so I added the 47K resistor, so it behaves almost like an audio taper one.

The way it works is that in the middle position you bypass both the tone and the bass-cut.
Turning it counter clockwise (towards 0) it works like a regular tone pot.
Turning it clockwise (towards 10) you progressively remove lows.

You can vary the value of the capacitor to get more or less effect.

That’s a cool idea. I have a FrankenStrat with volume, treble cut, bass cut. Works nicely, especially with bridge humbucker.
