Walrus Audio announced the MAKO MK2 series on September 25, 2024, a second generation of its D1 delay, R1 reverb, M1 modulation and ACS1 amp and cab simulator pedals¹²³⁴. The original D1 launched in January 2020, and the R1, M1 and ACS1 followed¹³.

All four pedals gain an OLED display underneath the six controls, which the maker says makes navigating settings more intuitive and helps track added secondary controls¹²³. Each now holds 128 onboard presets; MusicRadar reports the first generation shipped with nine onboard and 128 via MIDI². Walrus Audio also increased headroom and lowered the noise floor across the range, and rebuilt and fine-tuned the effect programs based on user feedback¹³⁴. Time-based effects gain onscreen BPM control and BPM readout²³⁴. All four have MIDI connectivity and USB for firmware updates and preset management, and can run in mono or stereo². Bass Magazine lists the enclosure size as 4.9 by 2.52 by 2.64 inches and power requirements as 9VDC at 300mA minimum⁴.

The ACS1 MK2 adds three amp models to the existing three, for six total: the Peavey 5150, Orange Rockerverb and Mesa Boogie Dual Rectifier, joining the Fender Deluxe Reverb, Marshall Bluesbreaker and Vox AC30¹²³. It also adds six cabinet models with impulse responses by Justin York of York Audio, a noise gate, a headphones output on mini-jack, and the ability to load user impulse responses via USB-C¹²³. The D1 MK2 adds a Grain Delay algorithm¹²³. The R1 MK2's six reverb programs were completely rebuilt, and it gains a size control²³⁴. The M1 MK2 adds a flanger setting to its chorus algorithm²³⁴.

US prices differ between reports. MusicRadar and Guitar World list the ACS1 at $449 and the D1, R1 and M1 at $399 each²³. Bass Magazine gives $449.99 for the ACS1 and $399.99 for the other three⁴. Guitar Pedal X lists all four at $399⁵. MusicRadar reported the series available now²; Guitar World reported the D1, R1 and M1 available to preorder³; Bass Magazine reported all four available for preorder at walrusaudio.com and through authorized dealers, with expected shipment starting in mid-October⁴.
