An easy and essential mod for your volume control to get more uniform guitar tone from 1 to 10.
Hand-soldered here in the UK: a 150K-ohm 1/4-watt resistor (1% tolerance) in parallel with a .001uF mullard mustard capacitor
Wire this simple mod between the input and output lugs of your guitar volume control pot, to smooth out treble
bleed. Get more uniform tone from 1 to 10, and a more rounded sound at low volume.
