Awesome Digitech RP 500 Multi Effects Pedal. I've used this for many rock shows and lately have been using it as an amp modeler and it sounds really good. Everything works great except one of the dials broke off. You can still adjust that particular setting; you just have to flatten your finger against it and turn. But it's all functional.
Make custom pre-sets, you have a plethora of amps to choose from, and there's a tuner, looper, and wah as well. Super versatile and great sounding multi effects pedal, especially for the price.
The original power supply had broken so I bought a replacement and it works perfect.
