hi, so just a few weeks ago I got my new bass and I went from 4 to 6 strings. I've been playing it since i got it and i know that floating thumb is required to mute 6string effectively. Although i'm getting a bit frustrated, because i can't mute all strings i need to mute. For ex. if i'm playing on c or g strings, my thumb is on a string, right? Then b and e strings are left unmuted and they start to ring.. If i put my thumb on e, then I mute both b and e strings, but then playing on c, g or d strings is a bit uncomfortable and freakin A STRING starts to ring! What do I do? I can't mute all 3 string at the same time! And what's more, playing chords now is a pain in the ass! I play chords with my thumb, index, middle and sometimes ring finger too, so i have no idea how to mute strings then..... Thank's for your help!
