I've been using nothing but the SP303 and my two guitars. It's crazy for my samples, I do the following: I plug in a guitar, make a sample, mark the sample, add effects, resample/rerecord and wham. That classic dirty "DJ Muggs" Temples of Boom sound that I've been trying forever to get. I could never get that sound from Ableton live (via pluggins), Maschine (VSTs after the 1.5 update). Who would have thunk it, so yeah I'm digging my ebay purches.

Thanks SP303!
