Mute Clamp Concept

[gimmeagig]

I noticed that the tuning can go sharp when I use a foam mute that I made with neoprene which I glued onto a wooden stick.
I suppose if I used less dense foam that might make a difference?

Some foams will have less effect, but that's sorta the nature of the foam mute- if it has enough pressure to mute the tone, it's gonna push you sharp. Even if you retune, intonation is affected. Of course if you are playing at fret 20 with a mute.... ;-)
