I have tried many picks over the years trying to find a consistency of feel and sound for acoustic play and the SPSR is the only one that gives me the return I am looking for for quality of sound variation - soft or loud - and durability of play that provides me with the confidence to continue playing with satisfaction.
These plectrums are very much an "Acquired taste"! They are just about the softest, most pliable, gentle guitar picks I know of. Then again, I don't know anyboby else who plays on .007 strings.

These are even better with a Mad Professor Forest Green Compressor in SUSTAIN mode - let the Amp do all the work ! (217346).
