The ACS1 is Walrus Audio's answer to "I need a real amp sound without a real amp," and it's the most capable thing on my board. Three amp voicings — Fullerton (blackface Fender clean), London (Vox chime), and Dartford (Marshall plexi grind) — each running into your choice of six cabinet IRs, with three of those slots loadable over USB with your own impulse responses.

It runs in full stereo, stores 128 presets, and has a dedicated boost footswitch with its own saved settings per preset, plus a three-band EQ and a room reverb to put the cab in a space. I've used it as a silent recording front end, as a direct-to-FOH rig, and as an always-on amp-in-a-box in front of a clean platform. It does all three convincingly.

Sold as-is. Please look closely at the photo — that is the actual item you will receive, and it is the best record of its condition. Expect normal scratches and scuffs consistent with a used piece of gear. Reverb condition grade: Excellent. Pedal only — no box, and no power supply (takes a standard 9V center-negative adapter).

These are $399 new and clean used ones sit in the $280–325 range. Priced to move because I'm not including the original box.
