There's a local amp and pedal builder by the of Dunwich Amps. Dude makes some awesome stuff. He decided to have some shirts made up, and I couldn't help myself. He dropped them off to me today.
The Wizard one (on the right) was done by a process of bleaching the design into the black fabric. It looks cool as hell! Anywho, figured I'd share. Here's links to some of his stuff... http://www.facebook.com/dunwichamps
