24 – Using the SV-1 | Selecting and editing the effects

Use the three EQUALIZER knobs to adjust the low, mid and high frequen-

cies. After having changed a knob position, you can return to the default set-

tings by pressing the corresponding knob.

WARNING: Extreme EQ settings may produce a very loud signal.

The SV-1 includes a stompbox simulator, that recreates the sound of a pedal

effect inserted before the ampliﬁer’s input. Use the TYPE knob of the PRE FX

section to select a different stompbox effect (compressor, booster, U-Vibe,

vibrato, tremolo or wah).

If the wah effect is selected, use the AUTO/PEDAL button to change between

Auto-Wah (LED off, ﬁlter changing automatically depending on the sound

and the playing dynamics) and Pedal-Wah (LED on, ﬁlter controlled by an

expression pedal connected to PEDAL input 2; if no pedal is connected, the

ﬁlter will be ﬁxed).

NOTE: Before using an expression pedal to control the wah, it is advisable to

calibrate it. See “Calibrating the pedals” on page 31.

You can change the speed of the modulation of the U-Vibe or tremolo effects

by using the SPEED knob, and the intensity of the modulation by using the

INTENSITY knob. To return to the default settings, press the SPEED or

INTENSITY knob.

NOTE: The booster stompbox may produce a very loud signal.

The SV-1 includes an amp simulator, to choose among a series of vintage and

modern instrument ampliﬁers. Use the TYPE knob of the AMP MODEL sec-

tion to select a different ampliﬁer. You can change the preamp’s volume

(therefore, its overdrive saturation) by using the DRIVE knob. To return to

the default setting, press the DRIVE knob.
