Right, the DISTX is a real distortion box. With the gain right down you can you can squeeze out some dirty blues, but this pedal's designed to be seriously cranked , and no surprise that's what it does best. When you push this pedal you can go all the way to death metal, but still retain note clarity. The three band EQ lets you shape your sound like a lot of amps, and then the ISF dial gives you the sound of every other amp, you've pretty much got every heavy sound you can imagine. It's got an emulated output which is pretty good for recording, and it's built solid to last. The only bad points are that it takes about 10/15 mins to warm up to it's best sound, but really it's worth the wait. Finally the 16v power supply is pretty awkward for pedal boards, there's only one that I've found that can provide this power, so most likely you'll need an extra plug socket for the power supply. However for the sound produced by the extra power, it's a worthwhile compromise, I most strongly recommend, well worth the money.
