(1) PRESETS
These switches instantly recall the settings stored in the corresponding PRESET 1-5
when pressed, press the active PRESET switch again will bypass whole loops. All
presets are stored in nonvolatile memory, will not be erased even without power supply.
(2) MUTE/CLEAN
This switch instantly shuts off the LOOP OUT (LOUT1&LOUT2) and switches the
INPUT to CLEAN jack, press it again will get back to normal operation.
(3) BANK UP / DOWN
BANK UP/DOWN switch increases/decreases the BANK, there are 10 BANKS
(A,b,C,d,E,F, G, H, I, J) available.
(4) LOOP1~6 Program Keys
These keys turn on / off LOOP1 to LOOP6 separately, the signal goes through the
LOOP when a LOOP is on( LED on), LOOP off (LED off) means the LOOP is bypassed.
(5) LOOP7~9 Program Keys
These keys turn on / off LOOP7 to LOOP9 separately.
(6) NUMERICAL BANK DISPLAY
It indicates the active BANK.

(7) BUF IN (Buffered Input)
Signal input via this jack is fed to a buffer circuit prior to being sent to the loops.
(8) DC Jack
5.5 x 2.1 mm type, use negative center DC 9V / 500mA power supply.
(9) NBUF IN (Non Buffered input)
This jack bypasses the buffer circuit and directly sends singal to the loops.
the BUF IN jack is automatically disconnected when a plug is inserted into it.
(10) LOUT1 and LOUT2
Output jacks for series loops (LOOP1 ~ 6), the input signal via buffered or non-bufferd
Input jacks reaches the two jacks via 6 series loops, LOUT 1 and LOUT2 jacks are
Internally connected in parallel.
(11) S1
This is send jack of LOOP1, connects to input jack of guitar effect.
(12) R1
This is return jack of LOOP1, connects to output jack of guitar effect.
(13) EARTH TERMINAL
Connect the commander frame to earth through this terminal.
(14) BUF OUT (ALWAYS OUTPUT)
Singal from INPUT goes through a buffer circuit, one branch feeds to LOOP1 ~LOOP6,
The other branch feeds to BUF OUT(A.O) jack.
(15) CLEAN
When LOUT is muted, the input signal via buffered or non-bufferd reaches this jack.
(16) IN7
Input of separate LOOP7.
(17) S7(N.C)
SEND jack of separate LOOP7, this jack should be connected to the input on effect
unit. When LOOP7 is on, signal from IN7 reaches SEND jack, enters external
effect then back to R7 (RETURN jack), finally reaches OUT7 jack. When LOOP7
is off, the signal from IN7 directly reaches OUT7.
This jack also functions as latching N.C (Normally Closed) switch which works
as footswitch to control amplifier channel. The jack is “closed”/“open” when LP7
is off/on.
(18) R7
RETURN jack of separate LOOP7.
(19) OUT7(N.O)
OUTPUT jack of the separate LOOP7, This jack also functions as latching N.O
(Normally Open) switch which works as footswitch to control amplifier channel.
The jack is “open”/“closed” when LP7 is off/on.(Note: Leave RETURN7 unplugged)

Guitar signal feeds into GEC9 input (NBUF IN or BUF IN), enters series
LOOP1~LOOP6 when MUTE switch is off, then outputs from LOUT1 and LOUT2.
If MUTE is on, the signal outputs directly to CLEAN jack.
The BUF OUT jack always outputs buffered input signal.
3- Recall Presetting and Bypass whole loop
Press preset switches to recall presettings, the corresponding
LED lights on when a preset is active. Press the active preset
switch again will bypass the whole loop, the corresponding
LED will be turned off.
Recall / bypass operation will not change the MUTE status.
5- Mute / CLEAN
Press MUTE /CLEAN switch to mute the LOUT and send input
jack signal to CLEAN jack, the MUTE status LED will turn on.
To cancel MUTE function by pressing this switch again.
MUTE function works individually, recall / bypass opertations
do not change MUTE status.
6- Bank UP/DOWN
GEC9 have 10 banks from A to J, each bank store 5 presets.
Press BANK UP or BANK DOWN switches to change the bank,
the numerical bank display blinks when the bank is about to be
changed. Press any preset switch to recall new bank presets.
7- Programming
Program keys are inactive when the pedal works in bypass mode.
(All presets LED are off), the keys will be active when a preset
is active, press the program keys to turn on/off corresponding
Loops, the loop status LED will be on/off accordingly. All loop
on/off status are automatically stored into non-volatile memory
which will be still available even the power supply is removed.

Configuration 2 - Separate loops as footswitch
In this configuration the separate loop send jack S7, S8, S9 are used to control the
amplifier channels. The amplifier preamp is connected to GEC9 LOOP1, makes it
possible to add modulation effects to the preamp.
