CONTROLS

LEVEL: Controls the volume of the pedal output. Turn it up

for loud, obnoxious in-your-gut bass or turn it down for

toughest speakers with a massive wall of sound. If you play

a chord, the effect is likely to cause a cosmic disturbance.

In simplest terms, plug the thing in and turn it up. The

sound is menacing but after significant hearing loss and the

passage of time, you won't notice a thing.

EXAMPLE SETTINGS

Distortion sounds are really a matter of personal taste, but

some example settings are shown here to give you a

starting point for creating your own tones.

When you set up the effect, use the LEVEL control to match

the distortion effect level with the level of the original input

signal. The control should be set so that there is a slight

increase in level when the effect is switched into the signal

path.

The BLEND knob controls the amount of distortion vs. the

amount of dry signal when the effect is on. To increase the

amount of distortion, turn the BLEND pot clockwise.

The TONE knob controls the post distortion high frequency

practice.

BLEND: Mixes the original sound with the distortion's post-

EQ sound. Turning this control clockwise increases the

amount of distortion blended with the original signal.

Turning the control counterclockwise can provide a nice

little touch of distortion if you don't want to get out of

control.

TONE: Controls the post-distortion high frequency EQ.

For less "bite" turn it down.

DRIVE: Controls the distortion gain of the bass sound.

Turning it counter-clockwise gives it a slightly distorted

sound. Turning it clockwise gives your bass a helluva lot of

distortion gain. This control packs some serious punch, so

use it with care!

FOOTSWITCH: Switches the distortion effect in or out of

the signal path.

LED INDICATOR: Lights when the distortion is enabled,

eq. Turn the knob clockwise to add more of that nice

"scratchy" tone, or just to annoy the ones you love.

The DRIVE knob controls the gain in the distortion section.

Turn up the DRIVE knob to increase the gain. This adds

more "edge" to the sound.

and is lit when the distortion is bypassed.

JACKS: Input, Output, Dry Output, AC Adapter (use the

DOD PS 200R power supply to eliminate the need for a 9

volt battery).

WHAT THE FX91 DOES

The FX91 Bass Overdrive is a distortion box designed for

bass guitar that allows you to mix distorted bass with

your original sound. It gives you thunderous low-end

power while retaining the punch you need to cut through

even loudest band. You could use a normal guitar

distortion box, but not only do they not have the bottom-

end punch you need, but they'll even roll off the low end,

giving it a whimpy "squished" sound.

The FX91 however, is sure to fulfill almost any need. You

can make it sound flubby and big, make it sneer like

death metal, or add just a touch of distortion for extra

bite.

CONNECTING THE FX91

Connect your guitar to the input of the FX91. Connect the

OUTPUT of the FX91 to your amp (or to the input of

another effects device you may running). To eliminate

the need for a 9-volt battery, attach the DOD PS200R

power supply to the AC adapter jack.
