Sound — 5
When not able to use my Engl Powerball, I try various SS amps (with distortion units) in conjunction to an 81/85 EMG loaded ESP Ltd F50. I must admit the sound of this pedal wasn't particularly impressive, in fact it reminded me of the cheap sounding Overdrive effects on the very amps I was using. Albeit this, it's lead tone weren't too shabby, much preferable than what it offers to rhythm. It lacked character and surprisingly, I found it couldn't really achieve any decent death metal overdrive... Regarding pedals, I much prefer the tone and feel of my other dist. Unit, the Boss ML2.
Overall Impression — 7
The drawback of the pedal lies not in its design, but in it's sound. Playing most metal genres, it reminded me a bit of Death's sound (the irony) but I couldn't get it to sound very dynamic or 'powerful', the coproduct of noise makes the result not very pleasing. For the price, I wouldn't really bear a grudge against it, but I'd much rather chip in some extra bucks and get something better. However I deem it makes a good beginner pedal for those in heavy metal.
Reliability & Durability — 9
It's a solid enough pedal with a metal construction, built to take some abuse, it hasn't given any trouble since purchase. For power it takes either an adapter or a 9V battery, which is good. For gigging it also has a mixer output, which is a neat feature.
Ease of Use — 9
The interface is simple enough for most people to use, you've got a level knob (like a volume meter for the unit) and high/mid/low controls where you can further tighten your equalization. Setting up the pedal is also very easy, you're good to go in seconds.
