Description

Blend pot variant for guitar controls. Based on https://www.circuitlab.com/circuit/za4mra/prs-custom-24-custom-wiring/

You can see a definite, -3dB+ ish drop due to the introduction of the blend pot. Bumping the volume and tone pots to 1M makes a difference, cutting this to -2.5db. This means the guitar will only sound 85% as loud. The proper way to fix this would be to also use a 1M blend pot (as the blend crosses the output over 500k resistors to ground twice, so the effect is the same as adding a 250k resistor to ground in your circuit). However 1M blend pots are hard to come by.

I think the variation in tonal character might easily be enough to make up for the volume loss, especially if you use a boost pedal you should still be able to hit the amp just as hard.
