The Walrus MAKO Series ACS1 is a powerful amp and cab simulator - designed to deliver authentic vintage amp tones in a compact, pedalboard-friendly format. Whether you’re performing live, recording in the studio, or practising silently - the ACS1 provides world-class amp modelling and speaker cabinet impulse responses for dynamic, responsive tone shaping.
At its core, the ACS1 models three legendary amplifiers, each inspired by classic British and American circuits:
- Fullerton - Based on the Fender Deluxe Reverb, offering snappy cleans and rich breakup
- London - Modelled after the Marshall Bluesbreaker, delivering harmonically rich drive and punchy mids
- Dartford - Inspired by the Vox AC30, providing jangly highs and saturated gain
The ACS1 features six onboard cabinet impulse responses, custom-engineered by Tone Factor and York Audio, ensuring authentic speaker emulation. Players can also load their own IRs via USB-C, allowing for customised tonal flexibility.
With stereo inputs and outputs, the ACS1 enables dual amp setups, allowing players to mix and match amps and cabinets for unique stereo configurations. The three-band EQ ensures precise tone shaping, while the adjustable noise gate and presence/resonance controls provide fine-tuned response.
Additional features include three onboard presets, with MIDI control for up to 128 presets, ensuring instant recall of favourite settings. The dedicated Boost switch adds extra gain and volume, perfect for cutting through a mix. The ACS1 also includes a headphone output, making it ideal for silent practice.
