hey, i just bought a thumb pick and i was wondering if my thumb is supposed to lose circulation a little(it kinda turns blue after a while...). haha, something tells me i bought one that's too small.
Quick fit trick:

Boil some water, and then let it cool enough so it won't scald you. Throw the thumb pick in there for a few minutes, then carefully extract it, and fit it to your thumb. Make sure you make it a little loose, because it will lose some of the shape as it cools.

Partscaster/Tele into a bunch of pedals, a Maz 18 head, and a Z Best cab.
