Introduction  
 
The Accel FX22 Command Center Switcher combines two great products together for a clean and easy to setup pedal 
board. This pedal board is primarily designed to switch multiple guitar effects pedals at the same time along with some 
amp switching functions using a single footswitch. Different combinations of effects pedals and different switchable amp 
settings can be stored on different patches allowing the player to easily change between multiple effects loops and 
switchable amp settings with the ease of a single footswitch.  When using your Accel programmable switcher pedal board 
it is important to understand which mode you are currently in.  There are two primary modes, “Program Mode” and 
Recall Mode”. Remembering this is foundational and will keep you from attempting to program a function when 
in recall mode or attempting to recall a loop when in program mode. At the end of the manual, there is a Glossary to 
help clear up any terms the user may not understand. Once the switcher is hooked up properly, the user should be able to 
go through this manual in about a half an hour or so and understand all the switchers functions. Be sure to keep the 
manual for reference, especially as a reminder for the lesser used functions. An instructional video is also available online 
at accelaudio.com that mirrors this manual teaching all the functions in an abbreviated form.    
 
FX22 Command Center Pedal Board Setup 
 
Step 1: Mount your power supply.  
 
There are 3 power supply mounting methods that are available depending on your power supply of choice and your 
preferred mounting method. (Route AC input cables through any one of the four 1 ¼”  strain reliefs)    
 
 
Accel FX Power Source 8 and FX power Source 10M screw mount options. 
 
  
 
Universal Power Supply mounting method “A”.  (3M Dual Lock using parallel strips)   
 
When two pieces of Dual Lock fasteners are pressed together, the mushroom heads 
interlock with one another, with an audible snap. When you have parallel strips of your 3M dual lock mounted to one 
end of your power supply surface and the other strips to your pedal board, do not try to pull your power supply 
straight off! It will be very difficult. Pull your power supply off at an angle or use a pry bar.

Universal Power Supply mounting method “B”.  
(Universal mounting bracket and 6-32 hardware sold separately)   
 
  
 
Step 2: Attach adhesive backed Hook and Loop and 3M Dual Lock Strips: 
(If you mounted your power supply using hardware, be sure you leave open area around the screw heads in case you 
need to remove your power supply in the future!)  
 
We recommend alternating your strips of hook and loop and 3M Dual lock strips as shown in fig. 1 below.  
 
If you are thinking about using two strips of 3M dual lock for one row of pedals, we recommend you test this idea by 
mounting your power supply under your pedal board with two strips of 3M dual lock. If you choose to go with all 3M dual 
lock, you will need to purchase extra 3M dual lock separately. For some people it will take a small pry type tool to remove 
a pedal in the center of your board. While this is definitely a more secure mounting, when it comes to repositioning or 
swapping out pedals it is not very practical.  
Using a combination of Hook and Loop and 3M Dual lock provides far superior pedal mounting than the standard 2 strip 
hook and loop method used in the past on most pedal boards, while providing a practical way to reposition or swap out 
your pedals. 
Caution: If you are using an Accel power supply or plan on purchasing a FX Pedal Board Universal Power Supply 
mounting bracket. Make sure you cut out around the holes you plan to use for power supply mounting.  
 
 
3M Dual Lock Mounting Instructions: (Read before using this product!) 
Mounting Instructions: 
Note: When using 3M™Dual Lock Reclosable Fasteners. To obtain optimum bond to any surface, apply above 68°F (20°C). All 
surfaces must be clean, dry, and free of oil, grease, dust etc. Remove protective liner and press firmly onto the substrate for full 
surface contact. 
Adhesive bond strength increases with time, as the adhesive flows into the structure of the substrate. Handling strength is achieved 
immediately. At room temperature, approximately 50% of ultimate bond strength is achieved in the first 20 minutes, 90% after about 
24 hours and 100% after about 72 hours.  Since the grip strength of 3M dual lock is much stronger than a standard hook and 
loop product (Velcro) the bonding strength of the adhesive is required to be much stronger. So be sure of the location where 
you want to mount it. It will be very difficult to remove once full strength is achieved.    
Caution: When applying hook and loop and 3M strips to your pedal, make sure you are applying them in the 
correct position so you will be mating the hook and loop strip on your pedal to the hook and loop strip on the 
pedal board and likewise the 3M Dual lock on your pedal to the hook and loop strip on your pedal board (hook 
and loop won’t mate to 3M dual lock and vise-versa.

Step 3: Cable Path feed through examples directly down to Switcher Looper. 
 
 
  
 
 
Switcher Looper Set up: 
1) Connect the effects pedals to the Accel programmable switch as shown under one of the “Typical 
Configuration Drawings” in this user’s manual, (pages 12 and 13). Make sure to use a 9V input at least 350mA.    
2) Reference the “Over View section (pages 5 – 7) for component and feature identification. 
3) Power up switcher.  
     
For this unit to function properly use only a 9V power supply between 350 - 500mA. 
(Warning: Use only a 9V power supply.  Do not use more than a 9V power supply, this will over heat the 
switcher and will not be covered under warranty)

(1)  BANK DN      
BANK DOWN switch 1(SW1);  
In “Recall Mode”, press this switch to decrease the bank number.  
In “Program Mode”, hit this switch to shift the programming between loop1~4 (“L” in LCD Display ) and loop5~8 (“H” 
in LCD Display). 
To toggle between “ Recall Mode” and “Program Mode” hold this switch down for a couple seconds. Check for more 
details in the “Programming Loops and Foot switches” section (page 4). 
 
(2) BANK UP 
BANK UP switch (SW2); 
In “Recall Mode”, press this switch to increase the bank number. 
In “Program Mode”, press this switch to program the amp footswitches (FS1/FS2). Holding down this 
switch will toggle between “Recall Mode” and “Active Bank Setup Mode (ABS)”, for more complete of 
the “active bank setup mode” (page 5). 
 
(3) A B C D 
In Recall Mode: 
Preset switches “A” “B” “C” or “D” recall previously programmed loops for those switches. 
(Pressing the same preset switch again will “Bypass” the switcher, as indicated by the blue led above the bank up 
switch).  
In Program Mode, “A” engages loop4 or loop8, “B” for loop3 or loop7, “C” for loop2 or loop6, “D” for loop1 or 
loop5. 
 
(4) TUNER / Mute 
When this switch is engaged, the OUTPUT jack will be muted and the TUNER jack connects to INPUT jack. 
     
(5)  NUMERICAL (LCD) DISPLAY 
In Recall Mode: 
 The numerical display indicates the active BANK. 
In Program Mode: 
“L” indicates loop1~4 are ready to be programmed, “H” indicates loop5~8 are ready to be programmed. 
In “Active Bank Setup”  (ABS) Mode: 
A blinking “Blue LED” above “Bank Up” indicates the ABS program mode has been activate. (See the “ABS Section on 
page 5  for programming the ABS Function). 
 
(6) Master Bypass Access 
     To bypass the effects looped into the switcher, simply press any active recall switch  
     “A, B, C, D” (the active switch will be indicated by a solid red LED above the switch). W hen this switch is  
     pressed again, that switches LED will turn off. A blue LED above the “BANK UP” switch will turn solid blue.  
     This will indicate that the switcher is in “Bypass Mode”. Select any switch A-D to exit bypass mode and enter  
     back into recall mode. (You cannot program the switcher in bypass mode). 
 
(7) LOOP on/off indicator 
 The indicator is on when a loop is engaged. 
 
(8) FS1/FS2 (Footswitch indicators) 
The indicator is on when FS1/FS2 is open, off when FS1/FS2 is latched. 
 
(9) INPUT  
Connects to Guitar. 
  
						

							7 
 
(10) TUNER 
Connects to tuner. 
 
(11) SEND & RETURN 1-7 
Loop pairs, connects SEND (S*) to guitar pedal input, RETURN(R*) to guitar pedal output. 
 
(12) OUTPUT 
OUTPUT jack of the switcher, the input signal reaches this jack via loop1~7. 
 
(13) DC Jack 
5.5 x 2.1 mm type, use negative center DC 9V / 350 - 500mA power supply (this unit will not function properly under 
350mA’s).  
 
(14) LOOP8 
Loop8 is a separate loop, FX LOOP IN8 is the input of this loop, SEND8 sends the signal and RTN8 returns it, 
FX LOOP OUT8 is the output of loop8. SEND8 also functions as latching N.C (Normally Closed) switch which 
works as footswitch to control amplifier channel while FX LOOP OUT8 also functions as latching N.O 
(Normally Open) footswitch. 
This is nice to have when you are using your amp to achieve your overdriven or distortion tones instead of a 
pedal, since most modulation and time based effects in general sound more natural when applied to the 
signal after it has been overdriven. However if you are using pedals for your overdrive you can simply place 
your time based and modulation effects after your overdrive pedal. In which case you can use Loop 8 in front 
of the amp as shown in Configuration 1 on page 12     
 
(15) FOOTSWITCH Jacks 
There are two footswitch jacks FS1 and FS2 which can switch the amplifier channel, The TIP and RING of FS1/ 
FS2 are normally closed (indicators are off), the indicators will be on when FS1/FS2 is open. FS1 is a stereo 
(TRS) jack, the ring of FS1 jack connects to the TIP of FS2, FS1 allows a stereo cable connection between the 
FX8 Command center and amplifiers which has a stereo footswitch jack
