The Zonkin' Yellow Screamer Mk II, a fantastic pedal by DuhVoodooMan. It is a BYOC pedal (built by my friend at DuhVoodooMan.com) with some cool mods, including MOSFET clipping and the capability to put the boost circuit either before or after the overdrive stage at the flick of a switch, for completely different sounds. All the pedal's details are this PDF Zonkin' Yellow Screamer and here is the main ZYS page. This is easily the best tube screamer I have ever used. It sounds fan-freaking-tastic!
