KORG SV-1 1.0 User GUIDE (EFGI1) - Scavino

10 – Controls and connections | Front panel
4 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 SV-1 offers. After selecting a pedal with the
TYPE knob, you can use the SPEED and INTENSITY knobs to adjust the pedal
effect parameters. 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 “Calibrating the pedals” on page 29).
NOTE: The parameters will be initialized when you select a different preset.
5 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.
