Enabling and bypassing the Voluum
The main footswitch
LED
shows the status of the Voluum effect.
When this
LED
is off, the effect is completely bypassed and the input (
IN
) is directly connected to the
output (
OUT
). This connection is known as a true-bypass connection because in this state none of
the Voluum electronics are connected to the signal: this keeps your original guitar/bass signal as
pure as possible. (Unless buffered-bypass mode is enabled, see “Custom settings” on page 33,
where the Voluum electronics are active, but have minimal effect on your signal.)
When this
LED
is on, the signal is passed through the Voluum and the output (
OUT
) is the effected
signal.
The effect is enabled and disabled by briefly pressing the footswitch. Alternatively, when the
footpedal is moved to the toe-down position, the effect will automatically enable. Note that this
feature can be changed using the custom settings (page 33).
Note that if the main footswitch
LED
is flashing, it means the V oluum is in foot-operated preset
selection mode (see page 13).
Footswitch LED
Off:
Effect is completely bypassed (the Voluum has no effect on your sound).
On:
Effect is active and the Voluum will affect your sound.
Flash:
Foot-operated preset selection mode is active. The bypassed/enabled state of
the Voluum does not change in this mode but remains in whichever state it was
in before this mode was activated.
True-bypass or buffered-bypass?
Over the years, there has been much discussion about which is better: true-bypass or
buffered-bypass. The answer is: it depends.
Buffered-bypass has the advantage that the low-impedance output of the buffer can drive
long cable runs without these cables affecting your tone.
True-bypass, on the other hand, ensures the effect has no impact on the instrument signal;
useful with large effects rigs where you may want all the pedals to be true-bypass to
minimuse their impact when bypassed.
Ultimately, you should use whichever bypass setting sounds best in your rig. It depends on
your instruments and the other pedals in your chain, and indeed, the order of these pedals.
