The Cannon

User Guide

The Cannon is a 2-in-1 mashup of a pair of classic fuzz circuits: the Tycobrahe Octavia and the
AstroTone Fuzz / Sam Ash Fuzzbox. This pedal was conceived by and created for Chicago-area
bluesman Toronzo Cannon.

Controls

Octavia Side (left):

Volume – As one would expect, this adjusts

the output level of the effect. Turning the
control counter-clockwise will cut the volume
level.

fuzz –This is the gain control for the Octavia
side.

AstroTone Side (right):

Attack – This controls the gain of the

AstroTone side.

Volume – You guessed it; this controls the
volume of the AstroTone side.

Power Requirements and General Care

Make sure that you use a 9VDC center negative 2.1mm barrel power supply to power the Cannon. This is the
industry standard power supply that most pedals use. If the power supply says AC on it, don’t use it. If you aren’t
sure that a given power supply will work, we recommend that you send us an email ([e-mail]
contact the dealer where you purchased your pedal.

Bypass Switching Operation

The Cannon offers three different bypass switching modes that utilize the two channels in
various configurations. The description sounds complex, but the operation is simple. Note that
the Bypass Mode LED indicator is always lit, even if the pedal is fully bypassed.

Mode LED Color Mode Name Left Switch Function Right Switch Function

Blue Indy Mode Bypass for Octavia Bypass for AstroTone

Green Flip-Flop Mode Master Bypass Toggles between Octavia / AstroTone

Red Cannon Mode Master Bypass Momentary Bypass of both Channels

Indy Mode (Blue)

This is the default bypass scheme that is active the first time you power up the pedal, but the
pedal will remember the last mode you were in the next time you power it up. The left footswitch
bypasses the Octavia side, and the right footswitch bypass the AstroTone side. Each side can
be used independent of the other, or both can be turned on simultaneously for stacking.

Flip-Flop Mode (Green)

Flip-Flop Mode is ideal for the player who wants to switch from low gain to high gain with a
single tap of the foot. In this mode, you can toggle between the Octavia and AstroTone sides by
pressing the right footswitch. The left footswitches bypasses the entire pedal. In this mode, only
one of the two channels is active at any one time.

Cannon Mode (Red)

The Cannon is a little bit different. Both channels are always on for high-gain stacking fun, and
like the Flip-Flop mode, the left footswitch is a master bypass. The right footswitch in this mode
acts as a momentary bypass switch, allowing you to go from high-gain to squeaky clean and
back again as fast as you can press the switch. This could be used for a stutter effect, or it could
be used to break out of a high gain riff to go right into a clean interlude and then back to the gain
as soon as you let your foot off the switch. Note: when the pedal is bypassed, the right switch
turns both sides on (momentary); and when the pedal is toggled on (not bypassed), the right
switch turns both sides off (momentary).

How to Change Switching Modes:

To change from one bypass mode to another, hold down both footswitches for a few seconds
until you see the LEDs blink. Then you can scroll through three modes with the left footswitch
(the bypass indicator LED will change color when the mode is changed) and use the right
footswitch to select the mode you want and return the pedal to normal operation.

Warranty and Support Information

At Function f(x), we stand behind our work. All of our pedals are warrantied against defective
parts and workmanship for 1 year from the date of purchase. If the footswitch fails or a pot dies,
we've got you totally covered (minus the cost of shipping to and from the repair location) during
the warranty period. The warranty does not cover damages caused by user error (wrong power
supply plugged in to the pedal or submersion in liquids, as examples). Function f(x) reserves
sole right to determine what damages constitute “user error.” But we're reasonable guys, so
don't sweat it. Further, just because damages are deemed to be caused by “user error” doesn't
mean we won't repair it; it just means that the repair may incur a fee to cover parts and/or labor.

After that initial 1-year period, we are still happy to resolve/repair any problems that should
happen to arise in our products, but there may be a fee assessed to cover parts and/or labor.
We will do our best to keep repair charges as low as possible. In the event that a full PCB
replacement is called for, be advised that this may take as long as 4-6 weeks if critical parts are
out of stock and need to be ordered. However, we will never ask you to pay any costs upfront,
and we will communicate the status of the work regularly.

If you have questions about your Function f(x) pedal, or if you need to reach us to discuss repair
service, please send us an email at [e-mail]
as we can (usually within 24 hours).

. We will get back to you as fast
