Exactly What I needed!

Perfect! I have a Vox AC30 for an amp. The clean and crunch sounds I get out of it are great, but I was having trouble getting a good BIG distortion sound. I tried a few other pedals, and nothing comes close to the RAT. This pedal sounds awesome with the AC30. The sound out of this thing is huge! I love it!!!

I Love Stepping on a Rat!

I've owned a Rat since 1984 and have since gotten the Duecetone. I can't say how much I love these pedals. I keep looking for others to come along. But I still go back to my Rat. Everything dirty in anyway that I've recorded, I've used the Rat. I'm planning to order another Rat II as a backup! I've heard mods work well for these pedals. I think they sound great just as they are. Hears to Rockin' the Rat!

Beautiful Tone

This is probably one of the best pedals I have ever had. The tone on this thing is just beautiful. I have tried it using single coil strat and a humbucker ibanez, in both cases the tone is amazing. From smooth to pasty distortion just by turning the knobs. Really classy sound.

Bad-*** Monster sound

I just received this pedal yesterday and plugged it into my Fender Blues Deluxe. I used my Strat (single coil) through this and it gave me anything from a classic rock tone up to a real heavy overdrive (think early Def Leppard, Sorpions,etc.)
Reading the reviews before I purchased this pedal, I expected a goood tone, but it surpassed my expectations! I was "WOWED" by the power and clarity it brought to my tone! Truly satisfying!
That was just the beginning. After running my Gibson Les Paul (Standard) through this it became SURREAL! Unbelievable power and tone. The overdrive is second to none! Flat out BALLS, but maintained the integrity of the guitar's original sound. I have never been this satisfied with my tone. I will NEVER give up this pedal. If I lost it I would place a RUSH order on it immeadiately. It is built like a tank and Pro Co offers the best warranty in the business. Check out thier site (proco.com). I can't wait to run this through my Marshall 40 watt combo! I can only imagine the sonic terror it will produce!
No, I do not work or represent Pro Co in any way, shape or form - but now I am a dedicated consumer.

The best distortion pedal ever.

I tried one of these some years ago,and I´m very obsessive with my guitar tone,at that time I knew very little about gear and tone,but still to this day,nothing comes close to its monstruous sound and great harmonic definition,you can go from Blackface combo to British stack and beyond;Years later gear has come and gone,but this little pedal is the only thing remaining,I want another one already!
