JamUp Plug HD

Digital Audio Interface for iPhone, iPad and iPod touch

Meet JamUp Plug HD

Mobile guitar players are becoming more and more sophisticated every day, what started out as amp/effects emulator apps—mainly used to practice at home—have now evolved into a whole new generation of professional tools for working musicians on the go. For guitarists that are particular about their sound, tone and expression, the new JamUp Plug HD ensures that signals are converted with the utmost depth and dynamics as well as least noise
