Duesenberg MULTIBENDER User Manual

The Duesenberg Multibender enables you to play authen-
tic sounding pedalsteel licks on nearly every normal electric
guitar or lapsteel with a flat top. You can raise or lower Indi-
vidual strings from 1 to 3 half tones (depending on the string
gauge used) by pressing with the palm of the right hand on
one or more of the multibender‘s levers, which is normally
done with a foot pedal or knee lever on a pedalsteel guitar.
The levers are attached to an axle behind the center sup-
port. The strings to be bent are fixed to the levers and then
run over rollers through the center support. Each lever has
two screws for adjusting the resting point and the amount
of pitch change.
MANUAL
If you wish to add or remove a lever, now would be the
best time to do this. Loosen the two Allen screws on the
end of the base plate and slide the axle to one side. When
adding an extra lever, don‘t forget to install the enclosed
washer which prevents friction between the levers. When
completed, slide the axle back in place and tighten the two
Allen screws.
Mounting preparation
First of all make sure that the height of the multibender‘s
bridge saddles (11-14 mm) is compatible to the given neck
angle on the guitar so that the action of the guitar can be
properly adjusted.
Please note: The metal ear on the right side of the multi-
bender‘s base plate is meant to be used on a guitar with a
tremolo routing and must otherwise be removed to avoid
damage to the surface of the instrument!
Installation on a body without tremolo routing
Before removing the original bridge, first measure the
distance between the nut and the bridge saddle of the high
e-string. This measurement is needed for the exact positio-
ning of the Multibender bridge.
Before positioning the Multibender it is recommended to
protect the respective area on the guitar top using masking
tape to avoid scratching the surface.
Place the Multibender on the guitar top so that the high
e-string saddle position matches the previous measure-
ment (see above). The front of the base plate should be per-
pendicular to the center line of the guitar. Then use a piece
of thread stretched between the nut and the bridge saddles
of the outer strings to center the bridge. When the distance
between the thread and the edge of the fingerboard is the
same on both sides, the bridge is in place.
Now mark the positions for the eight attachment screws
and drill the holes with a 2mm drill. Use the enclosed
screws to mount the bridge.
The basic equipment includes two levers. Theoretically
there is space for up to three additional levers, although
a maximum of three levers in total is recommended for
convenient operation.
Allen screws for securing the axle
Installation on a body with vintage tremolo routing
(i.e. Fender Stratocaster)
In this instance only the front six screw holes are needed.
A new positioning of the bridge is not necessary, because
the six original holes are in the right place. However, these
holes must be doweled and re-drilled with a 2mm bit.
If the guitar is equipped with a modern tremolo with a two-
bolt mounting system, the existing holes can not be used
for positioning the Multibender bridge. In this case follow
the instructions for installation on a body without tremolo
routing. It may be necessary to dowel the original holes.

Summary

Mounting Preparation

Bridge Saddle Height Compatibility

Check compatibility of multibender bridge saddle height with guitar neck angle for proper action adjustment.

Tremolo Routing Consideration

Remove the metal ear if the guitar does not have tremolo routing to prevent surface damage.

Installation on Body Without Tremolo Routing

Measure String Distance

Measure distance from nut to high e-string saddle for exact Multibender positioning.

Protect Guitar Surface

Use masking tape to protect the guitar top from scratches during installation.

Position Multibender

Align high e-string saddle with measurement; ensure front plate is perpendicular to guitar centerline.

Center Bridge

Use stretched thread between outer strings to center the bridge on the guitar.

Mark and Drill Holes

Mark screw positions and drill 2mm holes for mounting the bridge.

Installation on Body With Vintage Tremolo Routing

Use Front Six Screw Holes

Utilize the front six screw holes for positioning; no new bridge positioning is required.

Dowel and Re-drill Holes

Dowel original holes and re-drill with a 2mm bit for mounting.

Modern Tremolo System

If using a modern two-bolt tremolo, follow 'without tremolo routing' instructions.

Secure Under Tremolo Lip

Use the mounting bracket to secure the Multibender under the tremolo routing lip.

Cover Visible Routing

The metal ear covers the visible part of the tremolo routing.

Stringing the Multibender

Feed Strings Through Support

Align levers and feed strings straight through the center support under rollers and over the saddle.

String Attachment for Pitch Change

Attach ball-ends to lever for pitch raising or use front hole for pitch lowering.

Adjusting the Multibender

Lever Pitch Adjustment

Use threaded screws to adjust lever rest position and detune interval.

Adding Extra Springs

Insert extra springs underneath levers that lower pitch, clamping between pin and screw head.

Lateral Lever Mobility

Adjust front lever section mobility using a 3mm hex wrench after removing the front screw and spring.

String Height and Intonation

Adjust string height with 1.5mm screws; loosen third screw for intonation adjustment.
