Bassfire Hookup Diagram









Front panel operation

1.Input – Plug your Bass into this 1/4" unbalanced input using a TS cable.

2.Program Up/Down Buttons – Change the program number with these buttons. When pressed together, they put the unit into both Bypass and Mute modes and access the tuner.

3.Display – indicates bank and program, shows parameter values, and displays the pitch in tuner mode.

4.EFFECT Knob – puts the Bassfire in PLAY mode or EDIT mode. You are in EDIT mode when this knob is set to anything other than PLAY.

5.VALUE Knob – adjusts parameter values and program numbers; stores changes.

6.DRIVE Knob – raises or lowers the level of the distortion effect.

7.BASS Knob – adjusts the bass frequencies (independent of the EQ in the EFFECT section).

8.TREBLE Knob – adjusts the treble frequencies (independent of the EQ in the EFFECT section).

9.MASTER VOLUME Knob – controls the volume of the signal sent to the speaker, headphones, STEREO LINK OUTPUT and SPEAKER OUTPUT.

10.HEADPHONES Jack – Plug in your headphones using a 1/4" stereo plug.

11.Power Switch – turns the Bassfire on and off.

Rear panel operation

1.Fuse – Replaceable fuse. See the rear panel of the Bassfire for details.

2.Power Cord – Plug this cord into a proper AC outlet. See the rear panel for details.

3.FOOTSWITCH UP/DOWN INPUT – Plug footswitches into these 1/4" jacks. Footswitches serve the same functions as the Program Up and Down buttons.

4.EXPRESSION PEDAL INPUT – Plug an expression pedal into this 1/4" jack for easy control over EFFECT parameters.

5.AUX INPUT – Plug a CD player or other audio device into these RCA jacks and play along!

6.STEREO LINK OUTPUT – Use a 1/4" TS cable to connect this jack to the input of another amplifier for true stereo. The Bassfire provides true stereo output instead of the standard mono; many of the Bassfire’s excellent effects will sound even better when you listen to them in stereo. If you don’t have a second amplifier, you can enjoy the stereo effects by listening with headphones.

7.SPEAKER OUTPUT – Use a 1/4" TS cable to connect this jack to an external8-ohmspeaker. Doing so disconnects the internal speaker.


Exploring the Bassfire’s effects

Imagine having nine different stomp boxes at your feet. The Bassfire’s effects section works the same way: nine different effects modules are chained together in a sequence that you determine. You can control the parameters for each of those nine modules using the EFFECT,VALUE, andDRIVE knobs on the lefthand side of the front of the Bassfire. First though, take some time to familiarize yourself with the Bassfire’s default programs.

Turn the Effect knob all the way to the left to selectPlay. Now, play your bass and explore the programs by pressing theProgram Up andProgram Down buttons, twisting theValue knob, or by using optional footswitches attached to the rear of the unit.

You’ll hear programs ranging from clean and chorusy to grungy and downright nasty. If you have a pair of headphones, you might want to plug them in to the front panel headphone jack to hear the true stereo effects.

Modifying effects programs

There’s a lot more to the Bassfire’s effects than just what’s in the presets. The following pages provide a guide to the effects available.

Once you move the EFFECT knob out of thePlay position, you’re ready to start editing the effects. Once you change an effect, theEDITED LED on the bottom right of the display will light. From left to right, here are your options:


In this setting, the display shows you the current program number. This is the mode you should choose for typical live performances, as it allows you to switch programs easily via the foot pedals.

Indicates the bank letter and program number of the current program.

COMP/LIMIT (Compressor/Limiter)

Compression. Adds sustain and smoothness by lowering the dynamic range.

Limiting. Retains the original volume, but smooths out the loudest peaks.

Off. Turns COMP/LIMIT off.


DIST (Distortion)


A solid-stateclean amp sound; great for a crisp, no frills tone.


Warmer and thicker than the SS Clean setting.


Classic combo bass amp; works well for most playing styles.


Classic stage amplifier.


Sounds great with a touch of chorus in FX1 or FX3.


The lowest of the lows. Super-chunky.


The heavy sound of a high-powered,studio-standardbass





Dirty, slightly distorted bass sound.


A crisp and clean low-endyou’ll hear most often in country





A raspy synthesizer-likesound with a touch of resonance.


Turns off DIST.

DRIVE (increases or decreases the DIST level)

Increasing levels of drive/gain for the DIST module.

Pedal control of the drive/gain.

Indicates DIST is turned off.

EQ (Equalizer)

Varying levels of cut and boost for low, middle and high audio frequencies.

01-10: attenuated highs, emphasized lows

26-30: emphasized highs

11-20: less attenuation of highs, emphasis of

31-40: attenuated lows; emphasized



21-24: emphasized midrange

41-50: emphasized presence, lows

25: flat EQ curve


Turns off the EQ.

NR (Noise Reduction)

Left-handdigits: increasing levels of hum elimination (60Hz harmonic notch filters).

Right-handdigits: increasing levels of gating (silencing of quieter sounds).

Turns off both hum elimination and noise reduction.

CAB (Cabinet Simulator)

4 x 10” driver cabinet.

4 x 12” driver cabinet.

1 x 15” driver cabinet. Turns off cabinet simulation.


Classic Effects (FX1, FX2, and FX3)

NOTE: For all of the programs in the FX1, F2, and FX3 modules, choosing0 indicates the most subtle option, choosing9 indicates the least subtle option, and — where relevant — choosingP lets you control the effect with an optional external expression pedal attached to the back of the Bassfire.







Available In:



















Auto Wah. U1 – U4 sweep up; U5 – U9 sweep




















































Phaser. Higher values result in more feedback.










































Tremolo. Higher values result in greater depth.










































Cry. Adds ahuman-likecrying effect to the


















































Step Filter. Produces anarpeggiator-likesound.

























Slow Attack. Reduces the attack rate of the signal.

Auto Phase (). A phaser for which the delay is controlled by playing intensity.








Sub-Bass Synthesis. Addsultra-lowharmonics.







NOTE: Take care when using headphones or























external amps/speakers with this effect, as it adds









powerful lows that can damage certain equipment.


















Flanger. Shifts the pitch of the signal up and













down, creating a swirling effect.
































Rotary Speaker (L). Emulates the sound of the













classic rotary speaker.
































Chorus. Adds fullness to your sound.





















Pitch Transpose. Transposes the pitch either up or down. P0 – P4 transpose the pitch down a minor third, a major third, a perfect fourth, and a perfect fifth respectively. P5 – P9 transpose the pitch up in the same manner.

Variable Pitch TransposeUp.Transposes the pitch up from 0 to 2 octaves.







Variable Pitch TransposeDown.Transposes the







pitch down 0 to 2 octaves.




















Ring Modulation. Modulates the amplitude of











the signal, giving it a metallic sound.

























Auto Pan. Pans the signal back and forth from left











to right in the stereo field at a constant rate.























Classic Effects (FX1, FX2, and FX3) – Continued

Octaver. Adds a note an octave lower than the note you are playing.

NOTE: Take care when using headphones or external amps/speakers with this effect, as it adds powerful lows that can damage certain equipment.

Doubling. Doubles the signal with a slight delay.

Ping PonG Delay. Creates a delay that bounces back and forth in stereo.

Tape Delay. Emulates the retrotape-delayeffect.

Stereo Delay. A standard delay that occurs in stereo.

Echo. The classic echo effect.

Hall Reverb. Simulates the reverberation of a concert hall.

Room Reverb. Simulates the reverberation of a regular room.

Reverse Reverb (u). Creates abackwards-playingreverb that you hear immediately before you hear the original signal, instead of after it.

Plate Reverb. Simulates the classic “plate reverb” sound of a metal plate.

Off. Turns off the effects for this module.

DIGFX (Digital Sampling Effects)

NOTE: As with the programs in the FX1, F2, and FX3 modules, choosing0 indicates the most subtle option, choosing9 indicates the least subtle option, and — where relevant — choosingP lets you control the effect with an optional external expression pedal attached to the back of the Bassfire.

Sample Rate Decimation.Creates low-fi effects.


Bit Reduction. Lowers bit depth to create highly “digitized” sounds.


Off. Turns the DIGFX off.



Level. Indicates the program output level in 2dB steps, where 25 is unity





The order of the effects chain can be changed here.

This is the default order.

This one is the default order with FX2 and FX3 swapped to put the delay effects in the middle of the modulation effects.

This order places the cabinet simulator at the end.

This one is order 2 with FX2 and FX3 swapped.

This order is the default order with the compressor/limiter placed at the end, making this one ideal for recording.

This one is order 4 with FX2 and FX3 swapped.

This is the one to go for if you’re recording and want to sound like you’re running several effects pedals into an amp.

This configuration is order 6 with FX2 and FX3 swapped.

Storing effects programs

After you’ve created a configuration that you like, you can store it for future recall. To store your changes, press the VALUE knob and then turn the knob to select a store location. Press theVALUE knob again to store the program.

Copying effects programs from one location to another

Copying programs is easy. Just call up the program that you want to copy. Then, press the VALUE knob, twist it until you find the location where you want to store your copy, and pressVALUE again to store the program in its new location.

Restoring factory defaults for the effect settings

Once you have saved changes to a preset program, you can still recall the original settings. To enter the RESTORE FACTORY PRESETS mode, simply hold down the VALUE knob as you turn the unit on and then select the program to be restored (or AL for all programs). Press theVALUE knob to confirm your selection. The display will blink rapidly several times to indicate the restore was successful. Any program changes you have made will be lost, so you might want to copy the program to another location first.

To exit the RESTORE FACTORY PRESETS mode, just turn the EFFECTS knob. You can also turn the Bassfire off and then on again, without holding down any knobs or buttons, to exit the RESTORE FACTORY PRESETS mode.


Deferred program change

In normal operation, the Bassfire switches immediately to the program you select. However, in some situations — especially when playing live — you may want the ability to scroll through program numbers while remaining in the current program setting. For example, if you’ve got a clean and chorusy bass sound stored in program A3, and you want to switch next to a grungy sound stored in program C5, you don’t want to have to hear all the programs in between. In these cases, use the Bassfire’s Deferred Program Change mode.

While turning on the Bassfire, hold down either one of the Program Up orProgram Down buttons. Letters will scroll by on the display, spelling the word “deferred.”

In this mode, you can scroll through program numbers without having the program change each time. When you arrive at a program you want to use, press the Program Up andProgram Down buttons or both pedals at the same time in order to switch to that program.

To exit Deferred Program Change mode, turn the Bassfire off, and then turn it back on again without holding down any buttons.

Bypassing the effects

To bypass the effects section entirely, hold down both the Program Up andProgram Down buttons – or press both footswitches – for less than half a second. The screen will readby () to indicate that the effects have been bypassed.

You may now control the amplifier’s volume with the volume knob. Turning any other knob restores the effects.

Using the built-intuner

Press both the Program Up andProgram Down buttons – or press both footswitches at the same time – for more than half a second to enter both Bypass and Mute mode.

Play the open string you wish to tune. Use the following guide when tuning:
