Average at best

Usable, but not very versatile. Works less like a fuzz and more like a noisy distortion pedal. Goes pretty well with single coil pickups. Only goes one octave. Ideal for bass and lo-fi indie rock music, though I think J. Mascis used better gear back in the day. It cost me $35. You get what you pay for.

Needs Modding

For $35, this is some serious bang for buck, but the capacitor mod is essential to make it sound great.

Loud and noisy (in a good way)

Pretty decent sound for the price, use with battery otherwise it will make an unholy noise (as far as i know every one of these does the same, mine does too).
