Sonuus G2M

According to Sonuus, he G2M™ is a simple-to-use, highly effective, guitar-to-MIDI converter, and is “Universal” because it doesn’t need a special pickup mounted on your guitar, but instead simply connects to your guitar like any other effects pedal
or tuner.

We're told that it's a true plug-and-play solution for monophonic MIDI guitar designed to give accurate triggering with low-latency. It can be used to sequence bass lines and guitar solos.
