I play autoharp only...but my great fear is that I'll lose or break this big tortise shell guitar thumb-pick...wonder where I got it? Never see them any more...(I use a Sitar plectrum ..called a 'Mizrab'-- on my middle finger for playing melody...(made of bent wires)..allows me to strum in either direction as fast as I want...[also made a similar one out of brass, ala Kilby Snow, but it is much heavier])
