LPX combines revolutionary features with Gibson’s traditional construction quality and superior sound. It’s the most technologically-advanced guitar in the world—yet remains familiar and playable. You don’t have to adapt to LPX; it adapts to you. Tune your guitar strings automatically, including alternate tunings, in seconds ...

Preparation Accessories Checklist Your LPX is a complete system with all needed accessories. After removing the guitar case from the shipping box, take out the Accessory Pack in the bottom of the box. Check that between the Accessory Pack and guitar case pocket, the following are all included.

Pull the Gear Shift up (furthest from the guitar body) to apply power to LPX. Push down on the Gear Shift knob (pushing toward the body until it clicks) to turn off LPX. This stores the current tuning and sound for recall next time you power-up.

Insert the charged battery in the guitar. Check the charge of the other supplied batteries, and if necessary, charge them to capacity as you explore LPX. If you need additional batteries, use Samsung IA-BP80W (or equivalent) camcorder batteries. Low Battery Indications Depending on how often you tune, the battery charge can last up to two hours of continuous playing.

For optimum Robo-Tuner tuning speed and reliability, please use the correct gauge strings. LPX ships with the recommended string gauge set: High E = .009, B = .011, G = .016 (wound), D = .026, A = .036, low E = .046.
4. When tuning is finished, LPX automatically exits tuning mode, unmutes the audio, and returns to whatever patch was selected when you started tuning. A Gear Shift light flashes green to confirm the guitar is tuned.

D A D G B D Manual Tuning with the Robo-Tuners You can tune LPX’s Robo-Tuners by hand as an alternative to using Robot tuning technology. Caution! Never use a manual or mechanical string winding tool, or attempt to tune the Robo-Tuners manually while they are operating robotically.

Select Sound Banks Select Sound Banks LPX has 11 Banks (1-9, A, and B), which you select with the Gear Shift knob. Each Bank has five patches (1-5), also called presets, that you select with the 5-way Pickup Selector/Patch Selector. You can freely save, load, and edit patches with the included LPX Editor software.
Page 15
Alter Volume and Tone The silver volume knob controls volume, while the black Digital Varitone knob controls tone. The volume taper and Digital Varitone response are both customizable with the LPX Editor software. Page 15...
Patch Play Mode and Edit Mode Patch Play Mode and Edit Mode LPX has two playing modes. Patch Play Mode is LPX’s default mode. It provides “foolproof” playing on stage by locking out the sliders and most blue tog-pot functions—even if you hit them accidentally, your sound won’t change.
Page 17
Note: A slider will not take effect until it passes through the existing parameter value. If a slider does not appear to be working, move it back and forth over its full travel. Also, when editing Reverb and Echo parameters, there may be a slight delay between moving a slider and hearing a change.
Page 18
The onboard computer will calculate the delay time from these peaks. 5. Play LPX and determine that the delay time is correct. If not, repeat steps 1-4 and make you you strike the strings with sufficient force to create strong peaks.
The pedals can use batteries or the supplied AC adapter, and operate a minimum of 30 feet (10 meters) from LPX to a maximum of 100 feet. These devices need to recognize each other—a process called “pairing”—which is done at the factory.

9V battery occurs automatically. However, switching on the pedal with only a 9V battery is not supported. Setting Up the Pedals for LPX 1. Remove the Pedal Power/Data Connector, which carries power from the Pedalboard to the Switchboard, from the bottom of the Pedalboard.

Bone Link Up. The confirms that all devices are communicating. Note: If you turn off LPX (e.g., to save battery power or change batteries) this will stop communications to the pedals. However, turning LPX back on will re-establish the link automatically after several seconds.

Pedalboard Display When you rotate the Gear Shift to change Banks or the Pickup Selector/Patch Selector switch to change patches, the display shows the Bank and Patch in large type for about two seconds, then reverts to the default display. The default shows the following (numbers in the descriptions are keyed to the display image).

If you switch guitars or replace some system component, re-pairing may be necessary. 1. Set up the Pedalboard and Switchboard as described previously in steps 1-5 of Setting Up the Pedals for LPX on pages 19 and 20 (linked, AC power connected, and antennas up). However, they should not be powered-on.
Chapter 5: Red Bank Functions In addition to tuning and patch Banks, a third Bank provides utilities and customizations. It’s called the Bank because when you initially enter the Bank, the Gear Shift knob displays mostly characters. Select a Red Bank Function Select a Red Bank Function 1.

2. Push down once on the Digital Varitone knob. 3. Push down briefly on the Digital Varitone knob to toggle between Offset Mode (display shows O) or Strobe Mode (display shows (S). LPX stores this preference on power-down. 4. Rotate the Gear Shift knob fully counter-clockwise.

Also, the position where you press down on the string affects pitch. For best results, use a consistent force and position. During intonation LPX takes a little bit longer to detect pitch. This is normal, as LPX switches automatically to a special high-accuracy mode.
Page 29
Custom Tuning (Position = C, ID = C) LPX has eleven onboard tunings. The easiest way to create custom tunings is with the LPX Editor; however, if you don’t have access to a computer, you can create custom tunings within LPX itself, and replace onboard tunings with your custom tuning or tunings.

A=440Hz. For these situations, LPX can tune to any arbitrary reference. The basic process is to tune LPX to the desired tuning, adjust one string to the reference pitch, then instruct LPX to tune the remaining strings relative to the reference string.
Page 31
Also, do not use any strings which have frayed wraps at the ball end (LPX will not function if any part of the string touches beyond its insulated holder), and don't let steel bottleneck slides contact the strings during tuning operations.
Page 32
7. Repeat step 6 again if necessary. 8. Once the string tension is sufficient for LPX to read the pitch, upon being plucked it will start tuning the string to standard tuning. When it’s close to standard tuning, the associated string LED will shine blue.

Restore Factory Defaults (Position = full CCW, ID = red circle) This operation restores all factory defaults. Caution! Any custom patches or tunings you’ve stored in the guitar will be lost unless you’ve backed them up to disk using the LPX editor Page 33...

LPX. However, it also functions as a standard audio interface for Windows (ASIO 2.0, WDM) and Mac (Core Audio) computers. LPX Editor software gives you access to LPX’s audio engine and tuning capabilities. You can create your own sounds and tunings as well as modify existing ones, maintain a library of patches, transfer patches in and out of LPX, and much more.

300 times and charge it back up again before its useful life is over. If you play LPX and discharge it 50% during a concert, then charge it to full capacity, that is Page 36...
Page 37
If you play LPX every day and discharge it to 75% of capacity then charge it back to 100%, it would take four days before the battery would experience a full charge/discharge cycle. However, a battery has a finite life regardless of whether you’ve used up the full number of charge/discharge cycles—after about 2-3 years its internal resistance rises to the point...

Appendix C: Troubleshooting Appendix C: Troubleshooting If you encounter problems with LPX, Gibson recommends that you take it to an authorized service center. Although there are some procedures you can try yourself, be careful—if you have any doubt about your ability to do any of these fixes, please consult Gibson tech support.

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. Page 39...
