Open Box Walrus Audio MAKO Series ACS1 Amp + Cab Simulator Effects Pedal Level 1 Gold

The Walrus Audio Mako Series ACS1 Amp + Cab Simulator is a revolutionary tool for guitarists seeking to craft and control their tone. This innovative pedal offers modeled tones of three vintage amps—inspired by Fender, Marshall and Vox—and six cabinet impulse responses to pair with them. Onboard presets, stereo ins and outs, and MIDI capability provide a wealth of tone-shaping possibilities for live use, recording or practice. The ACS1 is a pedal destined to become an essential piece of gear for discerning guitarists everywhere.

Three Classic Amps to Suit Any Style

The ACS1 provides tones modeled after three amps that shaped rock history: the Fender Deluxe Reverb, Marshall 1962 Bluesbreaker and Vox AC30. Select between the clean headroom and chime of the Fullerton channel, the rich overdrive of the London channel or the jangly bite of the Dartford channel. Blend amps between the left and right channels or run the same amp through both using the L+R switch.

Cabinet Impulse Responses for the Perfect Match

Pair each amp model with one of six cabinet impulse responses for the ideal combination of amp and speaker tone. The ACS1 comes loaded with custom IRs developed by Walrus Audio to complement each amp model. Guitarists can also load their own IRs using the Walrus Audio app. Toggle between cabs using the ABC switch or access a second set of cabs by holding the bypass switch.

Shape Your Sound with Onboard Controls

Like an amp, the ACS1's volume and gain controls work together to determine the pedal's output level and overdrive, and you can boost them for added punch. Simulate recording in different rooms with the ambience knob, from a dead room at minimum to a large studio at maximum.

Save and Recall Onboard Presets

Dial in your perfect tone and save it as one of three onboard presets by pressing the bypass and boost switches simultaneously. Cycle through presets by pressing both switches together. Remove power to retain the last preset used. Access up to 128 presets via MIDI. The boost feature allows you to quickly jump to a preset level of volume and gain—set it by activating the boost and adjusting levels, then save it by pressing the boost switch again.
