User Manual

Amp Switch (Fullerton | London | Dartford) - The Amp switch selects between one of three classic

amp models built into the ACS1. Each amp’s circuit topography was meticulously modeled to bring

as much feel and character from the amp to the pedal as possible.

Fullerton: inspired by the classically bright and clear Fender

Deluxe Reverb. Crisp clean tones with

loads of headroom that players have come to love over the years.

London: Inspired by a 1962 Marshall

Bluesbreaker with a harmonically rich, valve-driven breakup.

Articulate and sensitive response.

Dartford: Inspired by the legendary jangly high-end tones from a 1960s Vox

AC30 with all the bite

and chime from the British Invasion.

Bypass Switch - Click to turn the pedal on and click again to turn the pedal off.

Bypass LED - Indicates if the pedal is on or off by illuminating solid when on, and off when the pedal

is off.

Boost Switch - The Boost switch, when engaged, applies a percentage volume and/or gain boost to

the current volume and gain settings of your preset. To set the boost amount, press the boost switch.

The LED light will ﬂash showing that the boost is on. Use the volume and gain knobs to set boost

levels. Press the boost switch again to conﬁrm settings. When you disengage the boost switch, the

pedal will remember your boost settings in the preset for the next time you engage the boost switch.

Preset/Boost LED - The Preset LED lights up the color of the selected preset – Red, Green, or Blue.

When a knob is turned, this LED turns purple to indicate the preset has been modiﬁed. When that

knob crosses its saved position, the LED changes back to the color of the currently selected preset to

let you know its last saved position. This is helpful when you want to tweak a parameter on a preset

but cannot remember where a knob was last saved.
