I like this pedal... I use it in combination with my Danelectro Fab Metal distortion. By themselves they're not the greatest, but together, the pedals sound really great... I can get something similar to a Trey Azagthoth solo with them and a little chorus and delay after that sounds nice. It's an interesting effect... It's more of a post-distortion enhancer/shaper in my rig, and I use it as my main distortion in combination with the Danelectro pedal.
The pedal does sound kind of noisy, but you can't hear it when playing, and I use a lot of effects which contributes to the problem... a noise gate, and possibly a hum eliminator could fix it.
Reliability/Durability:
Like I said, I got this used. It's working perfectly still... I am guessing this effect is *roughly* 10 years old now, and it's still working perfectly. (Boss... duh)
Ease of Use:
It's pretty straight forward, like most pedals...
It will take a bit of fine tuning to get what you want, but all you're doing is turning 4 knobs... I keep it mostly maxed out, except I change the level and distortion knobs around a fair amount.
I got mine used, so there wasn't a manual.
Customer Support:
I don't know... never had to talk to them.
Overall Rating:
I play all kinds of noise, experimental stuff, ambient, shoe gaze, black-ish/death-ish metal, rock, etc. etc. and this pedal is pretty usable for most of these. Just don't expect a monumental effect on it's own. try combining it with other OD/Dist. and see what you can do with it. Either way, it's one of the most used effects on my board right now.
