The compact JamLab interface connects easily to your computer via a simple USB connection, and features a 1/4" input for your guitar and 1/8" headphone/line output. The included GT Player Express software features amp simulation and virtual guitar effects for EQ, chorus, reverb, and more. GT Player can also play standard audio files, and can even slow them down--perfect for practicing and easy learning. You also get WAV drum loops from the popular ProSessions Sound and Loops Sample Library. Load them into GT Player in any order for an instant custom drum machine to jam with. Drum songs are also provided as MP3 files.
