Okay so i decided my metal mster is too muddy, its not really agreeing with my blues junior, so im deciding to get a new distortion pedal. I'm going to use it for mainly van halen, guns n roses, and metallica. I dont really have a budget, i used all my money on the tube amp. but lets say up to $200.
Yeah BYOC means build it yourself

Haha no worries man, there are always loads floating around on ebay and classifieds ads if you decide you want one
Marshall Jackhammer on Overdrive mode.

It works great with my Blues Jr

EDIT: If you test it out, remember to keep away from the Contour and Frequency knobs.
Or as someone on youtube reviewing it called them, "The Shit Factor" knobs.
