Sound — 9
When using this pedal, due to the extreme feedback I get on larger amps, I use a Marshall MG10. I use a Dean Razorback Cemetery Gates, or an ESP/LTD Viper 10, depending on the genre I feel like playing at any given time. The pedal has a very wide variety of sounds you can use, it's an excellent pedal for practicing with, and it has the ability to make great tones for almost any genre, from Death Metal, to Grunge, it even has an acoustic patch. I've found it to be a great pedal for things like Bush, Nirvana, Stone Temple Pilots, as well as more modern bands, like Disturbed, Bullet For My Valentine, or Avenged Sevendfold.
Overall Impression — 8
Being a guitarist with a wide range of playing styles, whether it be pinch harmonics and dive bombs, or palm muting and chugging, I've found this to be a great pedal in the time I've owned it. I would definitely buy another if I needed to, it's well worth the buy.
Reliability & Durability — 6
As mentioned in the "Sound" category, when plugged in to a large amp, this pedal seems to generate a ridiculous amount of feedback. Personally, I wouldn't bring it on any large shows because of that, You'd have a hard time winning over an audience if the can't hear you're playing over the ear piercing squeals you'd get. It is, however, a great pedal for practicing alone, with a small amp, or at a small show, maybe indoors, with a few friends.
Ease of Use — 8
I've had this pedal for about two years now, it's fairly easy to use for both beginners and experts alike. This was my first pedal, and I figured it out within minutes of getting it. Another useful feature that I love, is the built in tuner it has, while it may not be the most pinpoint accurate tuner in the world, it works well enough as a replacement in case you've lost your other one.
