I usually play the bass with fingers. Recently I've been wondering how do I produce sharp muted notes like those one does with a pick and palm muting. More specifically, I am trying to emulate pick bass sound like one we can hear on the 60's records, for example, in San Francisco by Scott McKenzie supplied by Joe Osborne. I've tried putting my right hand on the bridge and plucking strings with my right thump and index fingers (thump-down and index-up movements). This works for slow tempo, but I can't play fast this way. To avoid this limitation, I've tried alternating index and middle fingers still keeping the hand on the bridge. This doesn't sound well for me, either, as finger movements are very constrained in this position, and secondly, index and middle fingers give very different sound because the hand is rotated clock-wise to touch the bridge with it's fleshy part. Is there a common "academic" way to play muted notes? Should I try putting left hand fingers just on the frets to get the sound? Or should I go on with the right hand muting? Does anybody use alternate right hand picking (i-m) while keeping right hand on the bridge or should I give up this idea at all?
