My Crunch Box arrived yesterday. I got to play with it for a few hours through my Flexi 50. It's about the same size as my Timmy pedal. As soon as I plugged it up, I started twisting knobs in every direction. One thing is for sure about this pedal, it can get freaking loud if needed to be. I have it set up at 9:30 Volume, 9:00 tone and 9:30 distortion with the Flexi set pretty clean. This just fits my setup really well, but will change from day to day. Anyway..... I pulled up a few mp3's to jam along to (Hendrix, Michael Landau, Eric Johnson, Van Halen, AC/DC and some Yngwie Malmsteen). Van Halen, AC/DC and Malmsteen wasn't that hard to achieve at all. This pedal really nails that sorta tone. I put on Michael Landau's "Big Bulge" live version and got pretty darn close. The high end really nails that hairy Plexi sound. I let my room-mate hear the pedal and asked what he would describe the tone as..... he said very peachy. I was like yea... it's real furry. lol It has Plenty of gain on tap. Any amount of distortion Van Halen would use is pretty easy to capture. Thats a lot of gain in my opinion. Lower the mids on the amp and you can nail a really good hard/heavy rock tone "Alice N Chains" and so on. This pedal is worth the money big time. I use to own a ToneBone Hot British pedal, this bad boy is so much better in my opinion. It has more gain and a more amp like tone. The tonebone was just to smooth sounding, The Crunch box really captures the essence of a cranked plexi with a good treble booster in front of it.
