INSTRUCTIONS

OVERVIEW 

We may have finally caught bliss. This is the very famous five-knob, two 

germanium transistor fuzz we’ve always dreamed of collaborating with 

ZVEX on. In short, it’s a souped-up Fuzz Factory

 with digital control 

and a resonant low pass filter. Although the five knobs are named for the 

parameters over which they seem to have the most control, please don’t 

hold us to it. They are controls for various operating levels and biases, 

shaping you a personalized fuzz. Like all Chase Bliss Audio

 pedals, 

all of these settings can be stored in presets, ramped, or controlled via 

expression pedal. Every knob and switch is connected to a little digital 

brain while your guitar signal stays 100% analog and never gets  

digitally processed.

LPF

Sets the cutoff frequency for a low pass filter. All the way 

clockwise is open, no frequencies being cut. As the knob 

is turned counterclockwise high frequencies are removed. 

In the maximum counterclockwise position, depending on 

where the LPF toggle is set, most or all high frequencies 

are cut. 

AUX FUNC TOGGLE

This toggle selects the function applied to the signal 

when the AUX stomp is pressed. When the toggle is set 

to the STAB setting, the STAB control will be maxed out 

when the footswitch is activated. Setting the toggle to 

LPF will allow the user to change between the max LPF 

setting and the knob defined LPF setting each time the 

footswitch is activated. Finally, the AUX stomp can be 

used to close the GATE (max CW) by setting the AUX 

FUNC toggle to GATE.  Alternatively, if put the AUXPOL 

dip switch in “D” (down) the polarity of these functions 

will be reversed. Make sure you have the AUXPOL dip 

switch in the “UP” position by default. 

FAT TOGGLE

This toggle selects the amount of sub frequencies 

allowed into the fuzz circuit and changes the nature of 

the self-oscillation pitches. NORM is typical Factory

 

configuration. FAT and FATTER increases the sub 

frequencies, respectively. This means the pedal can 

oscillate at much lower registers, giving it some very 

interesting thunder broom synth qualities. This fatness 

lends itself particularly well to the bass guitar, and rips 

equally well on guitar.

VOLUME

 

Sets the output level.

DRIVE

Increases distortion when used as a “normal” fuzz and 

adjusts feedback pitch and tonal thickness, if you’re 

that kind. This control becomes meaningless when 

COMP is all the way right.

GATE (RAMP) 

When there are no dip switches assigned to ramp any 

controls, this knob controls the gate. Turn to right to 

eliminate squeals, hiss, and buzz. Stop just as they 

disappear, or use to tune in exact feedback pitch, if 

you’re that kind. Turning to the left opens the gate. If 

a dip switch is engaged for ramping, you can set this 

knob to control any of the five parameters individually 

or simultaneously (VOLUME, DRIVE, STAB, COMP, LPF), 

and have it either modulate (bounce) or ramp-and-hold 

(rise or fall) via dip switches in the back of the pedal. In 

this case, this knob controls the ramp time in which this  

takes place.

STAB

Use all the way right for classic fuzz and to avoid 

squealing. Turn left for fuzz that is more soft and 

squishy, as well as to create self-oscillation.

COMP

Adds attack characteristic when turned to left, which 

gets softer to right, and suddenly pinches tone when all 

the way right. Also use to tune in fat feedback fuzz, if 

you’re that kind. Lower the STAB and see what happens 

to this control.
