Cab Sim

Six amp models with cabinet IRs, OLED screen, room reverb, stereo I/O, and MIDI support.

The ACS1 MKII is Walrus Audio's updated amp and cabinet simulator featuring a 2-inch OLED screen for improved parameter visualization. Six amp models—Fullerton (Deluxe Reverb), London (Bluesbreaker), Dartford (AC30), Citrus (Rockerverb), and Tread (Dual Rectifier)—cover vintage through modern tones.

Custom cabinet IRs from Tone Factor and York Audio complement each amp model. Users can load their own IRs via the web app. Room, hall, and plate reverbs simulate acoustic environments from isolated booths to concert halls.

Stereo in/out, MIDI control, and 128 presets (via MIDI) make the ACS1 MKII practical for professional rigs. Presence and resonance controls are accessible through the menu system. A noise gate helps tame high-gain amp models. SHARC and ARM processors deliver pristine 24-bit/48kHz audio.
