Walrus Audio's Mako Series might might have a more minimalist paintjob on their enclosures but this line of high-end stompboxes offers a comprehensive features set on what is becoming a familiar format.

Pedals such as the Mako Series D1 High-Fidelity Stereo Delay and R1 High-Fidelity Stereo Reverb arrive in a plain metallic paintjob, and offer a dual-footswitch format that is around the same size as a Boss pedal.
