You'll need a razor-sharp trimming knife, a small steel straight edge rule, sharp long-bladed scissors, double-sided adhesive tape and a black computer mouse pad.
The side of the pad should already be straight. Measure up 3/8"
and trim a piece about 4 or 5 " long. Then cut your 4 mutes vertically from that.
Stick rectangular pieces of double-sided adheasive tape to the
bottom of the mutes. Make the adhesives slightly larger than the
mutes and trim them flush with scissors...long bladed allows the
trimming to be done in one neat cut. The adhesive tape doesn't
have to be black because your not really going to see it.
In relation to depth, the mouse pads are only about 4/16" (1/4") deep.The addition of the adhesive tape should bring them to approx 5/16".
Start with the G string and lightly position the mute just ahead,
and clear of, the intonation screw. Place the other 3 lightly in the same position all the way across. Use the steel rule to make sure they're in a straight line and make sure there is an even gap
between each mute before finally pressing them into place.
Clean the surface areas well before fitting.
Easy hey
