Description

Crafting your tone has never been easier with the Walrus Audio MAKO Series ACS1. This powerhouse pedal is an amp and cabinet simulator offering the sound and feel of world-class amplifiers, all packed into a compact, pedalboard-friendly design.

The ACS1 models three iconic amps that have shaped rock history: the bright and clear Fullerton, inspired by a vintage Fender Deluxe Reverb; the rich and harmonically complex London, based on the 1962 Marshall Bluesbreaker; and the jangly and biting Dartford, reminiscent of a '60s Vox AC30.

Moreover, the ACS1 comes loaded with six high-quality cabinet impulse responses (IRs), offering maximum tonal flexibility. And if you want to explore further, you can load your own IRs via the Walrus Audio app.

Customizable boost and onboard presets take your tone sculpting capabilities to the next level. The boost function allows you to quickly jump to a preset level of volume and gain, and you can also save up to three onboard presets for instant recall.

  • Three vintage amp models: Fullerton, London, Dartford

Critic Reviews

Review: Walrus Audio Mako Series ACS1

guitar.com

The Walrus Audio MAKO Series ACS1 stands out with its stunning tone and user-friendly design, effectively competing with established giants like the Strymon Iridium. Its vintage amp models deliver impressive sounds, particularly the Fender-inspired tones that sparkle and resonate beautifully. However, the reliance on presets—without a manual mode—might frustrate traditionalists seeking hands-on control. While it lacks some features, such as built-in effects and the ability to output digital audio, its versatility for silent practice and recording makes it a worthy addition to any setup. Overall, it offers quality sound that could entice even the most skeptical players.

Walrus Audio Mako Series ACS1 Amp + Cab Simulator review | MusicRadar

musicradar.com

The Walrus Audio Mako Series ACS1 Amp + Cab Simulator packs a punch with impressive amp tones that mimic classic models like Fender, Marshall, and Vox, all while fitting neatly on your pedalboard. Its compact design, MIDI capabilities, and headphone output make it a practical choice for gigging and studio use. However, it could benefit from more gain to enhance versatility, and the absence of a manual mode may deter some traditionalists. Despite these drawbacks, the ACS1 stands out for its authentic sound and ease of use, proving itself a valuable addition for both live performances and recording sessions.

Walrus Audio Mako Series ACS1 Amp + Cab Simulator review | Guitar World

guitarworld.com

In the realm of amp and cab simulation, the Walrus Audio MAKO Series ACS1 stands out with its trio of impressive amp models—Fender, Marshall, and Vox—delivering authentic tones ideal for practice and performance. Its stereo operation and MIDI capabilities further enhance versatility. However, while the pedal excels in most areas, a notable lack of gain options limits its ability to reach more aggressive sounds. Ultimately, the ACS1 offers great value for players seeking high-quality tones in a compact format, but those craving heavier distortion may need to look elsewhere.
