The SV-2 is a voltage-controlled volume pedal based on the vintage Boss Slow Gear. The SV-2's Threshold control determines how hard a note's attack must be to trigger the effect, while the Speed control determines how fast the note will swell to full volume. Many effects can be achieved just by manipulating these simple controls, from straight volume swells to bowing effects to tape-reverse simulation.
Combined with other effects, the SV-2 becomes a truly unique creative device. Since it is envelope-controlled, the Slow Volume works best when placed at the front of a signal chain. Try it in front of an HD-2 and MD-2 for haunting, "whale song" effects. Or, put it in front of a WR-2 for swelled-wah effects. There are no rules, so don't be afraid to experiment!
Note: Like an envelope filter, the SV-2 must be "played" correctly in order to achieve maximum effect. Phrases must be played in a tight, almost staccato manner, with space left in between notes to allow the effect to re-trigger and track each successive one.
With practice, the SV-2 Slow Volume can become an invaluable creative tool you won't want to do without!
