Over the years there has been a lot of talk about this pedal on here and I've never tried it. I had a walrus audio Iron Horse for a while which was supposed to be a modded rat and didn't really care for it because it took away the highs too much. This is a very Lively pedal I'm digging it a lot and I only played it for like 10 minutes. I wish the sweep was a little bit better but it gets pretty chimy and clean when you turn the Distortion all the way down but then goes to almost pretty much dimed to right away when you turn the knob up. It's pretty filthy though and I think I love it. The filter is pretty useful I'll definitely use something else for a low gain although with the Distortion almost all the way off is pretty useful as well. I'm pretty sure this will be my main distortion when I need to get heavy even though I play a much more mellow subtle stuff these days. I am pretty happy this pedal is quite responsive. How many of you still use a Rat.
