The [ACS1]™ is an amplifier and speaker cab simulator delivering the sound and feel of world-class amplifiers, complimentary speaker cabinets created by Tone Factor, and controllable room size. With the ACS1, players have expansive options to deliver their tone whether it's on stage, in the studio, or practicing at home. Simple controls, stereo in and out, onboard presets, and MIDI support make the ACS1 an immeasurable tool in a guitarist's arsenal. Players can also load in their own IRs and update firmware at walrusaudio.io.
Amplifiers
The ACS1 models three vintage amp styles crucial to music industry history designated by their places of origin. When running the ACS1 in stereo, one amp can be used through both channels or mix and match amps and cabinets on the left and right channels with the L + R switch. Simply choose the channel you want it to modify, select your amp and cab model, and set your levels. Then flip over to the other channel and choose your amp and cab settings. If you would like to use the same settings on both channels, set the switch to the middle or “+” and dial in all your settings. They will be duplicated on the left and right outputs.
Volume and Gain work together, similar to how they would on an amp. For example, increasing gain levels will also raise overall volume output so adjust the volume knob accordingly.
Fullerton is inspired by the classically snappy and clear Fender® Deluxe Reverb. Clean headroom that blooms into the fat, rich breakup that players have come to love over the years.
London is inspired by a 1962 Marshall® Bluesbreaker with a harmonically rich, valve-driven breakup. Perfect for sustained lead notes with tons of gain on tap and a punchy mid-ranged voicing.
Dartford is inspired by the legendary and jangly tones from a 1960s Vox® AC30 with all the bite and chime from the British Invasion. Higher gain settings offer up plenty of saturation that represent the loudness and punch of the original amp cranked
Cabinet IRs
The ACS1 includes six IRs custom engineered by David Hislop and Kenyon Reed at Tone Factor. Each IR has been created with vintage amps to deliver the best tonal representation possible.
The IRs that are included in this update are based on a 90’s UK-made AC30 6TB with Blue Alnicos, a Marshall JTM50 Tremolo Bluesbreaker 2x12 combo with UK-made 6402-cone G12M Greenbacks (16ohm versions that come in Marshall cabs, which are brighter than the 8ohm versions in Vox cabs), and a Vintage 1966 Fender Deluxe Reverb with it’s original Jensen C12NA.
Visit tonefactor.com/ACS1 to explore their new XR IR Collection and see all of the complete IR packs with more microphones and placement options.
Use the ABC Cab toggle switch to select your cab preference. Access the second set of cabs by holding down bypass while changing the cab toggle position.
Room Ambience
Simulate the size of the room that your amp and cabinet are in. At zero, it would resemble tracking your amp in an isolated environment with no reverb. At max would emulate a natural-sounding, large studio environment.
Presets
Save up to three presets onboard by dialing in your favorite sound then pressing and holding the bypass and boost switch simultaneously. Both LEDs will flash confirming your settings were saved. Cycle through presets by pressing and releasing bypass and boost simultaneously. The pedal will cycle through the three onboard presets - red, green, and blue. When power is removed from the pedal, it will boot up in the last used preset. Using MIDI, up to 128 presets can be saved and recalled.

Boost
A boost feature is available by pressing the boost switch. It allows you to quickly jump to a preset level of volume and/or gain. The boost LED will flash letting you know that it is active. To set the boost, simply click the switch on and adjust the volume and gain knobs to taste. Pressing the boost switch again will save your boost settings and return the pedal to its normal level of volume and gain.
