MONO-RAIL II w/Fishman®Piezo
Mono-Rail II w/Fishman® Piezo bridges
allow the bass strings to be isolated fro
one another by using independent bridge
plates for each string. the strings are
installed by lowering the ball end into the
bridge and hooking the ball end below
the string catch at the rear of the bridge.
Intonation adjustments can be made by
adjusting the
intonation
screws (A) at
the rear of the
bridge clockwise to move the saddle back, and
counter clockwise to move the saddle forward.

EQ Controls
The EQA-PZ system has separate EQ circuits for both the Magnetic Pickup
and the Piezo Pickup. The Magnetic EQ Circuit boosts both the bass and
treble frequencies simultaneously with a single control knob. The Piezo
Pickup EQ Circuit is a 2-band EQ
circuit and features a Treble EQ
knob on the body and a Bass EQ trim
pot inside the control cavity. The
Bass EQ trim pot is designed for "set
and forget" use. Turning the trim
clockwise boosts the bass
frequencies. Turning the trim
counterclockwise cuts the bass
frequencies.

Piezo Sensitivity Adjustments
The piezo pickup responds to individual string vibrations. However, different
string gauges and player techniques can cause individual string outputs to
sound uneven. To handle these variations, the EQA-PZ system allows the
piezo pickup sensitivity for each string to be adjusted so string-to- string
output levels can be properly balanced.
1) Set the Piezo Volume Knob all the way up and the Piezo Treble EQ Knob to
its center position. Internally adjust the Piezo Bass EQ trim 3to the center.
2) Using a small screwdriver, adjust the
Piezo Sensitivity Trims 1individually to
balance the output level of each string.
3) Turning the Trim Pot clockwise will
increase the output level. Turning the
Trim Pot counterclockwise decreases
the output level.
Note: If one string seems to have less output,
adjust that string’s trim pot all the way up, then
turn the rest of trims counterclockwise to
balance the output level.
The EQA-PZ system was designed to allow bassists to achieve various sound
possibilities by combining a magnetic pickup with the FISHMAN® Piezo-
equipped Mono-Rail Bass Bridge.
In addition to the Piezo Volume Knob and the Piezo Treble EQ Knob on the
surface of the instrument, advanced adjustments can be fine-tuned by
utilizing the following trim pots located inside the control cavities:
1Piezo Sensitivity Trims for individual string outputs.
2Piezo Output Trim to balance the master piezo signal with the magnetic
pickup.
3Piezo Bass EQ Trim.

Battery
The battery should be changed when the volume becomes low or the sound
becomes distorted. Use a new 9-volt alkaline (not lithium or carbon) battery.
The battery is stored inside control cavity (D). Inserting a plug into the jack
activates the power supply. Be sure to disconnect the cord when the bass is
not in use; this will prevent the battery from draining.

Balancing The Piezo Signal Output Level With The Magnetic Pickup.
To utilize both the magnetic pickup and piezo pickup sounds, the piezo
output level can be adjusted by a Trim Pot 2.
1) To determine output level of the Magnetic Pickup, set the Magnetic Pickup
volume at 10, the Magnetic EQ at center and the Piezo Volume at 0. If
needed, adjust the overall height of the Magnetic Pickup.
2) After the Magnetic Pickup height is determined, turn the Magnetic Pickup
Volume back to 0 and the Piezo Volume up to 10, and then listen to the
output level balance of both pickups.
3) If the Magnetic Pickup output level is louder than the piezo, turn the Piezo
Output Level Trim clockwise to increase the signal output level. To decrease
the piezo signal output level, turn the trim pot counterclockwise.
