The [ACS1] TM is an amplifier and speaker cab simulator delivering the sound and feel of world- class amplifiers, complimentary speaker cabinet IRs created by Tone Factor and York Audio, and controllable room size. With the ACS1, players have expansive options to deliver their tone on stage, in the studio, or practicing at home. Simple controls, stereo in and out, onboard presets, and MIDI support make the ACS1 an essential tool in a guitarist's arsenal. Players can also load in their own IRs and update firmware at walrusaudio.io. The ACS1 contains six amplifier models based on fan-favorite amps, each with its place in music history, and twelve cab IRs (Impulse Responses) designed by world-class designers to give you the best tonal representation possible. The stock IRs for the Fullerton, London, and Dartford amp models were custom-engineered by David Hislop and Kenyon Reed at Tone Factor, while the stock IRs for the Red, Citrus, and Tread amp models were designed by Justin York at York Audio. Amplifiers The ACS1 can mix and match stereo amp and cab combinations. Want to run an AC30-style amp on the left and an Orange-style amp on the right? Or perhaps a 5150 flavored amp in both channels but with two different cabs for a wider stereo sound? When running the ACS1 in stereo, one amp can be used through both channels, or these combinations can be run independently left and right if you choose, leading to powerful, unique amp tones.
