C, NO GUITAR PICK ON THIS PLANET WILL MAKE YOU A BETTER PLAYER!
Artificial tortoise shell for a tenner a pick?Sure my local petshop would sell you a terrapin for a fiver.
Bloody difficult though to do an arpeggio with a terrapin. I'd recommend a small mollusc for that.
The picks are reviewed in this month's Guitar Player magazine. It isn't on the web site yet though. Suffice to say that the reviewer is now using Red Bear picks!
Not all picks get lost, broken, or worn out. ;)
