If you love lush, vintage-inspired modulation, the PedalPCB Caesar Chorus delivers that classic chorus-and-vibrato vibe in a custom-built package. This circuit is a clone of the Walrus Audio Julia, this circuit takes you straight back to the ’80s, with plenty of control over your modulation character and depth.

This is a chorus that sounds like a chorus should: rich, vibey, and musical. One thing I particularly appreciate is that it stays at unity volume when engaged, so you can enjoy the modulation without an unwanted jump or drop in level. The controls let you dial in everything from subtle movement to more pronounced, swirling textures.

Custom Build & Features

• White 125B enclosure with custom Julia anime-inspired waterslide artwork.
• Protected with SprayMax 2K clear coat for a durable, glossy finish.
• Four white, 16mm Boss-style knobs from Love My Switches.
• Top-mounted enclosed jacks with a PedalPCB top-jack plate.
• DC jack secured with epoxy for added long-term stability.
• Mini toggle switch with a threaded-through dress nut for a clean, finished look.
• Blue 3mm rate indicator LED to the left of the footswitch, set in a clear Fresnel lens.
• Red 3mm bypass LED to the right of the footswitch, also set in a clear Fresnel lens.

The LED arrangement is intentionally reversed from the original Walrus Audio Julia, giving this build its own little twist.

A Note About the Toggle Switch

The sine/triangle SPDT on/on toggle provides a subtle change in character rather than a dramatic shift in sound. As other Caesar builders have noted, the difference can be understated. If you're looking for a chorus with controllable, musical modulation rather than a collection of radically different effects, this circuit has a lot to offer.

The Bottom Line

This is a hand-built, custom-finished chorus for players who appreciate classic modulation, DIY pedal craftsmanship, and artwork that stands out from the usual production-pedal crowd. Whether you're adding a little movement to clean tones or chasing that unmistakable ’80s shimmer, the Caesar is ready to find a place on your board.
