I have a few guitars with different 13-pin
interfaces that can connect to an Axon
AX- 100 that has its midi out running to
the midi in port on an M-Audio UNO,
which gets connected to my Linux box
running g2ghpro. The midi out port on
the UNO then runs into a PS3 Rock Band
adapter and into my PS3. A guitar hexa-
phonic pickup with 13-pin midi out is
required to run g2ghpro. The following
lists are of tested hardware that will work:
; Roland GK-3a.
; Roland GK-2a.
; Roland GK-3b.
; Graph Tech LB- 63 (any Graph Tech
piezo bridge will work if using the
; Godin Synth Access guitars.
Guitars with built-in 13-pin capability:
; Godin LGX-SA.
; Godin Freeway-SA.
; Godin LGXT.
; Roland Ready Fender stratocaster.
; Brian Moore i8.13.

Of the listed hardware, I use a Roland
VG- 99, Axon Ax- 100, Godin LGX-SA,
Godin LGX with Roland GK-3a and
custom-built Ibanez S540 with Graph
Tech LB- 63 and hexpander.
I’ve also tested g2ghpro with a Roland
GK-3a pickup running into a Roland VG- 99.
Others have reported using a Roland GK-3a
with GR- 20 and GK-3b with GR- 55 on a
bass guitar as well. G2ghpro currently is the
only solution for using a real bass guitar
in the game, as no official bass guitar controllers have been released at this point.
The Original Controller
Harmonix created two guitar controllers
for Rock Band 3 pro guitar mode. The
first controller released was the Mustang,
which is a “button” controller, with 102
buttons on the frets and six strings over
the body of the guitar. When I wrote
the initial version of g2ghpro, the
Fender Squier Pro Strat wasn’t on the
market yet, which is the other pro
guitar controller that works with the
game. So I had midi dumps only from
the Mustang to work with.
