So I’ve done a lot of messing around with foam mutes stuffed under the strings on my Precision. While listening to A LOT of Jamo tracks, I got to thinking “ I wonder if the rubber mutes under his bridge ashtray hardened up over the years?” because his tone seems to have changed and gotten even warmer and more growly on the E string. Anyway I played around with a lot of different stuff and this sounds pretty awesome through my v4b - not too muted and warm. It’s just cut down from a strip of leather from the craft store, threaded onto each string with tiny rubber bands. I tried different widths of leather and settled on about 3/8”. I also mounted a LEGO thumb rest with double sided tape for a more sharp attack sometimes. P.S. - I’ve been stalking this page for years, and I really appreciate you dudes!!
