PRE FX section
Here you can select the model of a stompbox (pedal effect). This lets you select one of
the six pedal effect models the SV-1 offers. After selecting a pedal with the TYPE
knob, you can use the SPEED and INTENSITY knobs to adjust the pedal effect param-
eters. To reset a parameter to the default value, press the corresponding knob. Pedal
effects are connected before the amp.
The AUTO/PEDAL can be used when the wah effect is selected. When the button's
LED is off (Auto mode), the wah effect's filter is set automatically depending on the
sound and playing dynamics. When on (Pedal mode), you can control the filter with
an expression pedal connected to the PEDAL 2 connector; if no pedal is connected,
the wah is set to a fixed frequency. Calibrating the pedal is warmly suggested (see "Cal-
ibrating the pedals" on page 30).
NOTE: The parameters will be initialized when you select a different preset.
❺
AMP MODEL section
Here you can select the model of amp (including cabinet). This lets you select from
six types of classic amp models, including the legendary VOX AC30TBX. Each amp
model also include a cabinet simulator that can be edited with the SV-1 Editor.
After selecting an amp with the TYPE knob, you can use the DRIVE knob to adjust the
preamp volume (therefore, the overdrive saturation). To reset the drive to the default
value, press the DRIVE knob.
The operating mode of the preamp and power amp, the response of the tone controls,
and their placement within the circuit will change depending on the type of amp you
select here, precisely replicating the exact gain and tonal character of the original amp.
The all-important power amp stage (class A or AB) and negative-feedback circuit (or
lack thereof) are also carefully simulated.
NOTE: The parameters will be initialized when you select a different preset.
