I have a Korg KP3 Kaoss pad dynamic effects sampler that is in perfect condition. I bought it expecting it to use it more as a DJ, but have found something more suiting. I have the proper power adapter and it still has the protective plastic sticker on the touch screen. You can use this with DJing, and live music. I've had some friends hook up guitars and use the loop function as well as the effects function. Pretty neat!
Trying to sell ASAP
