Sound — 8
Using a BC Rich ASM (The Deceiver) and a 10watt Marshall, it will produce the heaviest tones your ears are likely to hear. It is perfect for heavy, hard-hitting metal but it takes a bit of fiddling to get softer distortion. Any Slipknot fan will adore this pedal, without a doubt (although they would use a BC Rich Warlock to get closer to their sound).
Reliability & Durability — 6
A good hard-wearing pedal that will happily take the beating of a stage performance. It is reliable, but it is sometimes tempramental and needs several stomps to change channels (dist & clean).
Ease of Use — 6
The Warp Factor distortion pedal comes with three knobs; gain, warp, and level. Gain is obviously the amount of distortion. Warp is a tone knob that boosts mid-tones of your choice. Level is the level of output. So far, simple enough. There is also a sub button which boosts bass end, although it is not suitable for smaller amps. It's very easy to plug in and go. Input, output and power are the only sockets to worry about. From there you need do nothing but play. Most people, however would try to find a great sound and stick to it; this can be arkward as there are no marking on the knobs. The manual states the obvious and tells you what everything does, which isn't hard to work out.
