GRasPi is a 15W battery powered compact size guitar amplifier with comprehensive features and offers wide range of effects all powered by Raspberry Pi.

GRasPi harnesses the power of the Raspberry Pi to run open source app like Guitarix (or others) which, controlled from an external MIDI pedal, offers a very large variety of custom sounds to the musician. The long battery life allows a good autonomy even to street musicians, furthermore with appropriate software the MIDI input port can be used with a master keyboard and enable its use simultaneously with a guitar.

To interface with Raspberry Pi GRasPi uses the widespread WM8731 audio codec, so everyone can easily change the software according their needs. The best way to access the Raspberry Pi's desktop is via wireless with VNC, so you can experience the sounds you prefer and create your own presets. For your gigs setup you can simply use a MIDI pedal to handle them.

The small size and low weight makes it the perfect companion of your guitar or it can serve as an alternative when you don't have the opportunity to use your large and heavy amplifier. To learn more about the new GRasPi do visit their KickStarter page and make a pledge if you are interested.
