Query: Great Metal fix for poor musicians

I use this pedal with a guitar sound on my keytar/sound module combo, and I really gott'a say, this is a GREAT pedal for its price. Although the knobs "tone" and "gain" do little for first-time musicians that want to rip out face-melters right away, once those knobs are figured out (treble-y vs. bass-y, distortion level), you have a GREAT little pedal with a LOT of power.Just don't leave ANY cords in the input when you're done, the vampire energy it saps away will drain batteries (It runs on 9v's) quickly. Of course, if you're using a wall wart, you can chug, chang, facemelt and solo until your house runs out of power!
