We have two Jamstik models currently available, the Jamstik 7 (7-frets) and Jamstik+ (5-frets). In general, we say that the Jamstik 7 is geared towards learners, while the Jamstik+ is the better option for more experienced guitars players.
The main differences are that the Jamstik+ has string bend capabilities while the Jamstik 7 does not support string bend. Additionally, the Jamstik+ has a rechargeable micro-usb battery (8-10hrs per charge) while the 7 fret utilizes 4 AA batteries (70+ hours).
