Practicing guitar is more effective (and more fun) when you have something to play along with. Unfortunately, by the time you program your drum machine or sequencer, your inspiration is gone. DigiTech's SDRUM solves this dilemma. Simply dream up a groove, bang out a couple of bars on your guitar, and the SDRUM's BeatScratch technology will build a full drum accompaniment based on your performance. SDRUM leaves plenty of room for customization, with control over tempo, intensity, grooves, and sounds. You also get pads on the front panel for inputting patterns manually. Creating drum parts on-the-fly has never been easier than this! No box, but extra discount!
