OMB Introduction
OMB enables guitarists to take their guitar playing to the next level with three game-changing
features: auto-backup music in real-time, an instrument-swap mode, and a no-delay guitar-toMIDI mode. It’s the missing link between guitars and seemingly magical technology, unleashing
any guitarist’s sound—no matter the style.
Of course you want to start playing right away, but first take a moment to look over the following
points.
• The OMB system uses Bluetooth technology for your guitar and app to communicate.See
EMC and Certificate of Conformity on page4 for all of the specifics.
• The OMB system battery should provide you hundreds of hours of cable-free playing
(between charging). When the battery can no longer hold a charge, contact OMB Service for
instructions.
• All things come to an end, and, at some point, the curtain will come down on the electronics
in your OMB-powered guitar. See Responsible Recycling on page4 when that time comes.

You may find that a feature works differently than you expect or is not available on your
device’s platform. OMB is committed to continuous improvement, and every effort is made to
put things write in the next revision.
How to Use this Guide
We know: no one likes to read a user guide. So go ahead—jump in and start. We want you to
start enjoying your OMB experience right away.
However, to enjoy yourself to the full, you might want to look through this guide to see if you
missed anything, or if something we think is intuitively obvious is anything but. (Let us know;
we’ll fix it.)
At the beginning of a section a short introduction discusses what is to be done, and it often
includes an identification of parts. A list of the parts is shown with capital letters in triangles
(A, B, C) keyed to the illustration below.
We hope that you'll be able to understand what to do just by looking at the illustrations. If some
step isn’t clear, look at the written instructions, which are keyed to annotations in the
illustration.
At last count, OMB enhances eight different types of guitars—and more coming. Thumbnail
drawings indicate the location of parts or features where they might differ, on your guitar, from
other models.

Safety
There’s a reason why we’ve put in this chapter, and it’s not to warn you about getting blisters on
your fingers from playing too long. (But you might want to lay in a supply of adhesive bandages
just in case.)
The information here is important to you and to your environment. So take a moment and look it
over.
The standard operating temperature for your OMB device is 86°F(30°C)
J
Battery Information
OMB products are powered by rechargeable LiPo batteries.
The batteries are not user-replaceable. If the operating time of your OMB guitar becomes
sluggish, or if you see shorter intervals between recharging, contact OMB Service for
information about how to have the battery replaced.
Attempting to change the battery yourself will violate the warranty and may damage the OMB
N
device. If you replace the battery with the incorrect type you run the risk of explosion.

The OMB Upgrade Kit
The OMB Upgrade Kit is for those guitarists who want to use OMB but love their own guitars too
much to play any other. The OMB Upgrade Kit works on most electric and acoustic guitars with
steel strings.
Installing the OMB Upgrade Kit is not very complicated, but it still has to be done correctly, and
in the right order. But we've tried to make everything clear and simple.
The OMB Upgrade Kit, and all OMB-powered guitars, can be switched to right-handed fingering
by single setting in the OMB App, so no special hardware adjustments are required during
installation. See Settings on page33 for more information.
Almost everything you need is included in the OMB Upgrade Kit. All you have to add is a soft
cloth, a bit of your favorite guitar cleaning solution, and about thirty minutes.
Oh—and one more thing: a soldering iron that can be adjusted to 660 °F (350 °C).
If you’re not acquainted with the terms “cold joint,” or “insufficient wetting”—if you don’t own
your own soldering iron—you might not want to experiment on your guitar for your first
soldering project. So find an electronics-savvy friend, or a trusted guitar shop, to take care of
this part of the installation for you.

Preparing Your Guitar
Before beginning to install the Add-On Device, remove your old strings, set them aside, and
then get your guitar ready as follows:
1 Take the fine steel wool from the packaging and very gently remove any corrosion or grease
from the surface of the frets. Remember to include the fret edges on both sides of the
fingerboard.
Be careful not to scrape the finish off of the frets.
N
2 Use a soft cloth moistened with your favorite cleaning fluid to clean the fingerboard, taking
special care to remove any residue of the steel wool.
We recommend that you do not use alcohol for cleaning your guitar.
J
3 Continue cleaning the side of the neck, directly below the frets…
4 …and finish up with the other side of the neck.
When your guitar has dried thoroughly continue on the page indicated according to your guitar
type:

Attaching the Add-On Device to Bridge-Pin Acoustic Guitars
In this step you will modify the Add-On Device for your guitar, depending on the height of your
bridge and the level of the bridge pins. If you have a pinless bridge guitar go to Attaching the
Add-On Device to Pinless Bridge Acoustic Guitars (page 13).
1 With a pair of scissors, cut the flex connector on the first perforation after the large set of
holes. Discard the excess where your community collects recyclable electronics.
2 Temporarily place the Base on the body of the guitar so the holes on the flex connector line
up with the pin holes on the bridge.
3 If the level of the flex connector is suitable to the height of the bridge, you’re finished with
this step. Go to page 11.
4 However, if you own a guitar with a higher bridge, the flex connector will not fit comfortably
on top of it. In that case…
5 …remove the adhesive backing from one of the pieces of the Add-On Device adhesive
strip…
6 …and attach it into the bottom of the Base.

2 Set the Base on the body of the guitar so the holes on the flex connector line up with the pin
holes on the bridge.
3 Gently put the first string through the flex connector, taking care not to rip or damage it.
Most nickle-coated steel strings are compatible with OMB technology. However, we
J
recommend that you use the strings provided in the OMB Upgrade Kit.
4 Lock the first string in place with its pin. Again, take care not to rip or damage to flex
connector.
5 Continue stringing your guitar in the same way.
6 When you completed the last string slightly angle the base upward…
7 …remove the adhesive backing, take the adhesive strip…

Attaching the Add-On Device to String-Through Body Electric Guitars
In this step you will attach the Add-On Device to your guitar, which includes the means to
prevent your strings from touching any metal part of your guitar. If you have a hard-tail bridge
electric guitar go to Attaching the Add-On Device to Hard-Tail Bridge Electric Guitars (page 18).
If you have a Tune-o-matic bridge electric guitar go to Attaching the Add-On Device to Tune-o-
matic Bridge Electric Guitars (page 20).
1 With a pair of scissors, cut the flex connector on the third perforation after the large set of
holes. Discard the excess where your community collects recyclable electronics.
2 Take a clipper and cut the bracing member off of the String-through spacer block, and then
discard it.
3 Now trim the end of each of the exposed tubes so that theyhave a sharp narrow point. This
point eases the passage through the guitar string holes in the next step.
4 Continue with the rest of the exposed tubes.
