I am the UK distributor for the Sonuus range of products.

Punkfolkrocker is correct in that the G2M (guitar to MIDI), b2M (Bass to MIDI) and i2M (Guitar/Bass to USB - MIDI and original signal) can all be used with other instruments.

They are monophonic but we have had users successfully try the devices with wind instruments, violins, and even voice. Where microphones have been used (rather than a pickup), it has sometimes been necessary to route the signal through a mixer or pre-amp.
