EQUIPPED!

Thank you for choosing the Fishman SBT. Although it is a very simple and basic passive pick-

up, the SBT will reproduce the full, natural response of your instrument. Please follow the

installation instructions carefully. Special attention should also be paid to the PLUGGING IN

section to ensure the best sound from your pickup. If you have any questions, please contact

The SBT Series pickups are economical "stick on" style pickups that can be mounted on any type

of acoustic stringed instrument equipped with a flat soundboard. All three models are crafted to

sense the microvibrations of a soundboard. Each is a practical alternative to more expensive

bridge mounted units that require the services of a repairman for installation.

The Model SBT-C is recommended for easy installation on classical guitars, steel string guitars,

dulcimers and similar stringed instruments. The Model SBT-E features the Fishman

Switchjack™ and is recommended when a permanent installation is desired. The Model SBT-HP

is specifically for harp and piano.

INSTALLING THE MODEL SBT-C

PARTS

•

SBT-C Pickup with 1/8" Shielded Jack

•

(3) Double-sided Adhesive Pads

•

Adhesive-backed Jack Holder

•

Felt-covered Strain Relief Clip

•

10' Instrument Cable

PREPARATION

The model SBT-C may be mounted onto a classical guitar, a steel string guitar, a dulcimer and

similar stringed instruments. The installation may be performed either on the outside of the instru-

ment or inside the soundhole where the transducer will be out of harm's way. In instruments with

small soundholes, dulcimers, for example, internal installation may not be practical.

As a general rule, the transducer should be mounted over a freely vibrating location and not over

a "dead" structural brace. The exact location for best results should be determined by experimen-

tation.

SBT Series - SoundBoard Transducer

1. Determine the approximate location of

the transducer by measuring about 1.5"

(3.8 cm) below the bridge and a 1.5"

(3.8 cm) below the highest pitched

string and note the position where these

two measurements meet. This will

serve as a test location (Fig.1).

2. Apply an adhesive pad to the shiny brass face of the transducer and mount at the location

indicated in Step 1. The transducer wire should follow the grain of the soundboard and point

toward the soundhole of the instrument.

Check the location by plugging in the pickup and listening. Should the position prove unsatis-

factory, move the pickup in 1/4" increments, and re-test, until you find the best position.

Carefully slide a guitar pick or credit card between the transducer and the soundboard to

release the foam adhesive. Residual adhesive should then be removed from the brass sur-

face of the transducer.

CAUTION: TO PREVENT DAMAGE TO THE TRANSDUCER WHEN REMOVING THE

ADHESIVE PAD, DO NOT PULL THE WIRE OR BEND THE TRANSDUCER.

3. Once you have found the "sweet spot" for the pickup, mount it at the same spot inside the

instrument.

4. Mount the adhesive backed jack holder to the inside of the instrument adjacent to the sound-

hole (Fig.2).

5. Insert the jack into the jack holder and plug the instrument cable into the jack (Fig.2).

6. Attach the felt-covered strain relief clip to the soundhole (Fig.2).

NOTE: The felt-covered clip can be bent to accommodate different soundhole thicknesses.

OPTION: PERMANENT TRANSDUCER MOUNTING

Although excellent results are obtained by using the adhesive pads, an increase in overall fre-

quency response and output will result when the transducer is bonded to the soundboard with a

"hard" adhesive. We suggest a gap-filling cyanoacrylate such as Loctite "Black Max™". Note that

such a procedure is permanent and irreversible; removal may result in damage to both the trans-

ducer and the inner surface of the soundboard.

INSTALLING THE MODEL SBT-E

The Model SBT-E is designed specifically for classical and steel string guitars when a permanent

endpin-style jack is desirable. We strongly recommend the services of a qualified repairman pri-

marily because a hole must be drilled in the instrument.

Follow the same procedure as the Model SBT-C on page 3 to mount the pickup element.

Prepare the Endblock

There are two ways to widen the endpin hole to accept the endpin jack:

Slow and Safe

If you have the time, this is the preferred way to enlarge the endpin hole. Remove the endpin and

widen the hole to size with a 15/32'" (11.9mm) reamer, available in the US & Canada through

Stewart MacDonald, 800-848-2273, part #4323.

Quick & Clean

The objective here is to drill out the hole with the endpin or other suitable plug in place. You may

remove a loose endpin and refasten it in the endblock with cyanoacrylate glue before starting the

procedure.

SBT-C Installation Continued

Note: We do not recommend this method for instruments with brittle ornamental veneers

(ex: abalone) around the endblock.

1. Apply masking tape around the endblock area to protect the instrument.

2. Locate an X-Acto saw blade 1/16" (1.6mm) away from the body and saw off the endpin.

3. Centerpunch a guide hole in the center of the trimmed endpin.

4. Drill a 1/8" (3.2mm) pilot hole through the endblock.

5. Line up a 15/32" (11.9mm) Spade bit in the pilot hole and begin drilling. Maintain a perpendic-

ular plunge in relation to the instrument. Use steady (but not heavy) pressure, especially as

the drill exits inside the guitar.

6. To avoid damage to the instrument, let the drill come to a complete stop before removing it

from the hole.

Install the Pickup

1. Insert the pickup in the slot and then strip and tin the wire ends.

2. Unscrew the shielding cap on the jack to expose the solder terminals. Thread the pickup wire

through the shielding cap.

Gently bend back the strain relief/sleeve tab to gain better access to the Tip terminal.

3. Solder the pickup "hot" wire to the Tip terminal, which is the shortest of the three tabs.

Solder the pickup shield to the ground tab on the jack. Gently tighten the strain relief.

4. Refasten the shielding cap to the jack.

OPTION: PERMANENT TRANSDUCER MOUNTING

Although excellent results are obtained by using the adhesive pads, an increase in overall fre-

quency response and output will result when the transducer is bonded to the soundboard with a

"hard" adhesive. We suggest a gap-filling cyanoacrylate such as Loctite "Black Max™". Be aware,

however, that such a procedure is permanent and irreversible; removal may result in damage to

both the transducer and the inner surface of the soundboard.

Wiring Options with the Fishman Switchjack

The Switchjack T-R-S-S (Tip/Ring/Sleeve/Switch) stereo switching endpin jack

allows simultaneous stereo operation and battery switching for active pickups. This

new configuration simplifies stereo wiring with many pickup combinations that were

once incompatible.

To gain better access to the Tip, Ring and Switch terminals, gently bend back the

Strain Relief/Sleeve tab, before you begin to solder.

Pages 7 & 8 illustrate the various wiring options made possible by the Switchjack.

Installation Guide

Fasten the Jack in the Endpin Hole

Follow this sequence when installing the endpin jack:

1 - Shielding Cap

2 - First Large Hex Nut

3 - Large Dress Washer

4 - Star Washer

5 - Guitar Endblock

6 - Small Dress Washer

7 - Small Dress Nut

8 - Strap Button

The jack should protrude at least 5/16" and no more than 11/32" outside of the guitar body for

proper fit. After fitting the small dress washer and nut over the end of the jack, insert the 3/32"

allen wrench through the small hole on the end of the jack. Tighten the nut with the 1/2" open end

wrench while holding the jack in place with the allen wrench. Thread and hand tighten the strap

button.

NOTE: With the strap button in place, the end of the jack

should protrude slightly, so that when a plug is inserted, it

will snap securely in place.

INSTALLING THE MODEL SBT-HP

The Model SBT-HP is designed for harp or piano.

FOR HARP MOUNTING

1. The approximate pickup position will be between 1/3 and 1/2 the soundboard's length, starting

at the bottom of the soundboard, 1" out from either side of the center brace. The resulting

intersection of the two measurements provides a good test location for the transducer.

2. Apply an adhesive pad to the shiny brass face of the transducer and mount outside the instru-

ment, at the location indicated in Step 1. The transducer wire should follow the grain of the

soundboard and point toward the bottom of the instrument.

3. Plug the pickup into an amplifier and experiment with the vertical location of the transducer. If

you detect boominess or feedback, relocate the transducer higher up on the soundboard. In

no case should it be necessary to mount it higher than 1/2 the distance. Use increments of

about 3 inches.

CAUTION: Removal for relocation should be performed by gently sliding a thin plastic credit

card between the transducer and the soundboard.

4. Once you have found the "sweet spot" for the pickup, mount it at the same spot inside the

instrument.

5. Plug the instrument into an amplifier. If boominess or feedback occurs, relocate the transduc-

er as detailed above.

6. Remove the protective film from the bottom of the jack holder and mount the holder in a con-

venient location. We recommend a location on the base of the instrument, if possible. We do

not recommend mounting to the soundboard.

FOR PIANO MOUNTING

A single SBT-HP mounted on an acoustic piano soundboard is an effective means of providing

high volume amplified sound reinforcement when used in conjunction with one microphone. The

microphone should sense the bass register of the piano while the transducer’s signal, when mixed

with the microphone signal, will provide punch and clarity to the middle and upper ranges of the

piano.

The SBT-HP should be mounted to the piano soundboard at a location adjacent to the higher

strings. For example, on a grand piano the transducer should be placed directly on the sound-

board within the third-largest ranges of the piano.

For additional instructions, see the instructions above for mounting the transducer to a harp.
