For a cheap pedal, it may not be that powerful as a distortion pedal, but if you combine it with other pedals it can give you a nice boost for your solos, or, you can use it to create some noise in your guitar, something like a fuzz
Considering that at worst case you've invested in a solid 3 Knob enclosure that you could easily gut and rebuild, and at best case you've spent between $20-30 on a pedal that is generally pitted against other pedals ranging from $30-50 and comes out as a unique and interesting option, I'd say this pedal is worth picking up. It is apparently a Guitar Center exclusive from around 2010, and is actually billed as a "Metal Distortion". There aren't really any metal tones you could get out of it, as it isn't very compressed nor does it have much sustain, two things that are really what you're looking for with a good "Metal" circuit. I would say that this pedal is actually more interesting than any of that, and for quite cheap. I've found success using it as a semi-clean boost with a little bit of treble color, as a guttural sounding distortion for chugs, a rippy full gain fuzz-like tone for solos, and even been able to find a happy medium that is akin to an overdrive or tube distortion. The point I'm trying to make is that this simple little circuit is very well made, very cheap, and very versatile. I have seen quality products from BBE throughout the years, and this cheapy doesn't disappoint. Again, at worst case you're spending just a little bit more than you would to purchase a blank enclosure with which to build your own pedal, so if you think of this is a very cheap investment, getting lots of mileage out of it is worth a shot. I certainly am enjoying folding it into my sets!
