Inspect the tuning peg that doesn't work. If its case is rotated, rotate the Robo-Tuner head
back to its original position—this should fix the problem. Then, tighten the nut to make sure
the Robo-Tuner stays in this position.
Caution!
Avoid overtightening—do not exceed 1
ft/pound torque maximum.
I removed the A, G, and (high) e strings but now the tuning system doesn’t work.
To get a “tighter” rhythm guitar sound, some guitarists remove these strings so they can’t
be hit accidentally. However, with LPX the strings carry low voltages and data, as well as
provide grounding. The E, D, and B strings are ground. The A, G, and high e strings carry a
positive voltage and data. By removing those three strings, there’s no way for the tuning
system to provide data on how to tune the strings.
The string LEDs are flashing white, and tuning doesn't work at all.
A white flashing string LED indicates a short circuit. The strings carry power and data to the
neck, so even if only one string is touching a hardware part (bridge, tailpiece, even a fret
bar) or another string, the tuning system won't work. Also note that if the Gibson "G" on the
neck electronic cover does not start flashing once you activate the system, it’s likely that
there’s also a white LED flashing on the Gear Shift knob to indicate there's a short circuit,
and therefore, no power going to the neck electronics. Please check the following:
The string ball ends must not touch the tailpiece at all.
The strings must be in the middle position of each string bar.
Look at the tuner posts; the strings must not touch each other, so cut all string ends
close to their posts.
Check the tailpiece and bridge height, then adjust if needed.
When I tune the Robo-Tuners manually, the process seems extremely slow.
The gear ratio in the Robo-Tuners is very high, so you need to turn the tuning peg many
times to get one complete rotation of the string post. This is one reason why Gibson
recommends using the Robot tuning options, especially when re-stringing, as the process is
fast and efficient. For more information, please see the information on Robotic string-
changing starting on page 33.
LPX doesn’t seem to connect to the G-Node interface.
Unplug the stereo cable from the LPX, wait a few seconds, then plug it back in again. This
solves most connection problems.
