This i9.7P.13.USB features midi on all 7 strings, 6 at a time, selectable via a set of mode switches on the back plate. Since all guitar synth products only recognize 6 strings at a time, this guitar features two modes to give the 7 string player the ability to have real 7 string Midi and all of the creative possibilities.
In the first mode it sends strings 6E thru 1E.
In the second mode it sends strings 7B thru 2B
It has full piezo acoustic on all 7 strings in both modes and also feature our built-in iGuitar.USB system.
