He plays a custom Kamaka tenor, with an extended scale length,
compensated bridge, extra-wide frets (for sustain) and radiused
fretboard. My friend Fred Fallin got to play it before Jake picked it
up at Kamaka. A luthier friend got a good look at it when Jake played
here in Grass Valley CA last summer. His specs are pretty much what I
like, too, although I prefer a standard scale length.
