2-2. Programming Loop Combinations
1) If the PROGRAM is not currently selected (i.e. if the red PGM indicator is not lit) press the rear-panel MODE switch to select the
PROGRAM mode (the red PGM indicator will light).
The PROGRAM mode is selected by default when the power is initially applied.
2) Each of the unit’s footswitches corresponds to one of its four loop programs. Press the footswitch you want to program (PGM1/L1~
PGM4/L4) and confirm that the corresponding blue indicator lights.
3) After engaging the desired PGM footswitch press the rear-panel MODE switch to switch to the DIRECT mode (the green DIR indica
tor will light), then use the footswitches to turn the loops ON or OFF as required to create the required combination.
4) When the desired loop combination has been set up use the tip of a pen or similar object to press the recessed rear-panel STORE
switch. The blue footswitch LED will flash to indicate that the setup has been stored.
5) Press the rear-panel MODE switch to return to the PROGRAM mode (the red PGM indicator will light) and confirm that the specified
combination has been programmed for the selected footswitch (press the footswitch and watch the LOOP indicators).
6) Repeat steps 1 through 5 to program the remaining footswitches as required.

4. Feature Details
4-1. Inputs
●
VZ IN (VITALIZER INPUT)
The VITALIZER circuit converts delicate incoming guitar and bass
signals to more resistant low-impedance signals that maintain
their original sonic quality during subsequent switching and rout-
ing (signal level remains the same).
●
IN (INPUT)
The low-impedance output of the VITALIZER circuit can change
the sound of some fuzz pedals and other effects. The IN jack
bypasses the VITALIZER circuit for situations in which a change
in sound is undesirable.
4-2. Series Loops
Loops 1 through 3 are connected in series (one after the other).
Signal switching is accomplished via precision mechanical
relays. When a loop is OFF the corresponding SND output is
muted so that no signal is sent to the connected effect unit. This
eliminates the possibility of unwanted oscillation due to crosstalk
when high-gain effects are used. All loops are S.C.T (Single
Contact True-bypass) type circuits, so when a loop is bypassed
the signal passes through only a single relay circuit for maximum
reliability and sound quality.
4-3. Separate Loops
Loop 4 is totally independent, and uses the same type of precision
mechanical relay as loops 1 through 3 for switching. In addition to
functioning as an independent loop, the separate loop SND jack
can also be used as a latching N.C. (Normally Closed) switch, and
the OUT jack can be used as latching N.O. (Normally Open) switch
for remote amplifier channel switching. This loop is completely
independent, right down to the ground line, so you can use it as a
control switch without having to worry about ground loop prob-
lems. The separate loop can be used as a mute loop, an A/B
switcher, and other utility functions. When the three series loops
aren’t enough for your system, you can patch the series loop OUT
jack to the separate loop IN jack to provide a fourth series loop.
4-4. VZ THRU (VITALIZER THRU)
Signals input via the VZ IN (VITALIZER INPUT) or IN jack are
processed by the VITALIZER circuit and output via the VZ THRU
(VITALIZER THRU) jack at all times. The VZ THRU jack can be
connected to a tuner to allow tuning while playing. The VZ THRU
signal is isolated from the main signal path so that the main sig-
nal will not be affected even if a short or other malfunction occurs
in the tuner cable or tuner.
