A great solution for tone freaks who want the purest tone possible without sacrificing the versatility of your guitar. Very smooth roll, so one might want to put a piece of foam between the pot and the knob to increase friction a bit.
Causion: Only use these with push-on knobs! I made the rookie mistake of fitting one of these with screw on knobs, which bent the shaft severly out of shape. I don't have the tools to fix it so I'll probably give it away to a guitar tech, who may just throw it away. Don't make my mistake!
