> mute off the back duplex > area with masking tape You should never use masking, duct, duck, plastic tape to silence duplex scales. You may use _fresh_ electrical tape or better still use SILLY PUTTY. Whatever this stuff is made of it will not leave a residue, corrosion or deposit on the strings. Do not leave it there for an extended time, you will have a frustrating time getting it all out again. Not hard, just time consuming. Fun stuff to play with aa well, when you get bored tuning. Newton
