Wyndham,

it goes with the usual 13-pin cable, the one that you can connect with a Roland GK-2 or GK3 esaphonic pickup, or with a Godin guitar, or a Carvin MIDI guitar, or a Roland-ready Fender Strat and so on.

If you want something less expensive, then you can buy the Sonuus G2M (Universal Guitar to MIDI Converter). But of course a solution such as the StringPort is much more complete.

Ciao!
