About 6 months ago I quickly cheked out a conventional electric guitar (second hand) that had a Roland digital pickup (MIDI) mounted near the bridge. The guitar was well priced but I discovered that I'd also need a Roland interface box to plug it into, about $US 150 as I recall.

My guitar Pro Shop tells me that they work well as a MIDI instrument. From my perspective, if I were to use a guitar as a MIDI input device I'd want to make sure that I could get normal guitar effects such as bend, vibrato and slide effects, plus use it as a conventional instrument. I got the impression that you could connect this Roland pickup to just about any stringed instument of suitable size - could be very wrong though.
