Used Walrus Audio MAKO ACS1 Amp Simulator + FX Pedal

The Walrus Audio MAKO Series ACS1 is a powerful amp and cab simulator packed into a sleek gold enclosure. Designed for direct recording, live rigs, or silent practice setups, it delivers three classic amp voicings (Fullerton, London, and Dartford) with stereo cab IRs and room ambience control. It’s a must-have tool for tone shaping without an amp.

Whether you’re plugging straight into a PA, audio interface, or running silent on stage, the ACS1 brings authentic amp response and massive flexibility. With MIDI support, stereo I/O, and preset capability, it’s ready for pro-level workflows.

As always, this used pedal has been tested in-store to ensure it’s working perfectly. We buy, sell, and trade used gear daily at Music Go Round—bring us your extra pedals and level up your rig!
