M-Audio JamLab JamLab turns your PC or Mac into a personal guitar system without the need for any other hardware except your favorite guitar. 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 effects boxes for EQ, chorus, reverb and more.

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. JamLab is ideal for traveling, limited space, and keeping both your budget and the neighbors happy.
