fantastic pedal!


fantastic pedal. very easy to use. lots of different sounds to mess around with.



good upgrade box for amateurs


This box is a great upgrade for someone looking to improve their stock of effects. Its not necessarliy professional grade like a Visual Sound or a Tech 21, but it definitely delivers high gain distortion needed to play any kind of metal. The only problems I had were there wasn't enough low end when I kicked one the top boost channel. I model my sound around the mids, similar to many punk bands and 80's metal, so having shrill highs in my sound pretty much just gives me a headache. I also found it time-consuming to dial in the right tone and gain I wanted. I also found that when I turned the volume down on my guitar it got really muddy sounding and lost a lot of clarity. I would keep it in my arsenal prmarily for stage use and practice since its not a particularly expensive piece and it is very durable and resistant to roadwear. But I would not use it for recording.

Don't Get Foolde


When i saw the reviews online for this pedal i thought hey this will be a great pedal. I was wrong. There is way to much feedback that comes from this thing. Unless you play an extreme form of metal i don't recomend it.

Best Distortion Pedal on the Market!


I just got this pedal a few days ago and my father (who has been playing guitar for over 30 years) says it is the best one he has ever heard. In my opinion, this pedal will completely destroy any other distortion pedal out there. One of the SLIGHT downsides is that once you get it, you have to do quite a bit of messing around with it to get just the right clarity and distortion setting.

metal to the max


This pedal lays all others to waist. I absoulutly love the tone, unlike a lot of pedals i have tryed this one gets you that nice classic palm muted metal sound. Its great for playing stuff like metallic, megadeth, preist, maiden, ect. Also the top boost was a cool feature it come in hand during solo hamer-onstaping ,and the like

The best ditortion pedal out there


This thing simply Rocks!,....I got it last week, the same day i reharse and then to the show...People couldnt understand how does my sound changed from heavy to mindblowing harmonic/colorfull/etc/etc...I use a 7 band eq pedal and it shapes fantastic the signal that comes out from this pedal. My recomendation, buy it, u wont regrett it. I am so happy with it. I was looking for this sound for many years but you only can find it on expensive tube amps, and now here in a little pedal. This one blows the others, boss, digitech, etc.

awesome pedal


I got this pedal for my birthday.i couldnt wait to bring it home.the salesman suggested it so i got it and it was the one of the smartest things i ever did. It has great sound and can make any guitar sound heavy.You can get many tones out of it. From real sharp to real muffled.Perfect for metal.




great pedal


I just picked this pedal up. It is awesome if you are looking for some classic thrash/death metal tone. I love it
