Acetone California Swirls (CSW-01) 2025 - New

Dive into lush, vintage modulation with California Swirls, an all-analog chorus pedal that captures the warm, swirling textures that defined classic rock, new wave, and grunge tones. Built around a genuine bucket brigade chip for authentic analog warmth, this pedal delivers rich, three-dimensional chorus effects that add depth and movement to your sound without ever sounding synthetic or digital.

The California Swirls specializes in that thick, watery modulation character that made chorus an essential effect in the late ’70s and ’80s. Its carefully voiced circuit produces smooth, liquid swells with a slightly dark, organic quality. It is perfect for shimmering clean arpeggios, thickening up rhythm parts, or adding that signature wobble to lead lines. The chorus effect is unmistakably present without being overpowering, sitting beautifully in a mix while adding satisfying width and dimension.

Simple three-knob operation puts intuitive control at your fingertips: Cutback adjusts the speed of modulation from slow, sweeping waves to faster, more animated swirls, while the Surf knob determines the intensity of the effect.

The bucket brigade technology ensures the warm, slightly compressed character that digital circuits simply can’t replicate. There’s a gentle, musical quality to the modulation that enhances your tone rather than competing with it, making California Swirls equally at home on clean jazz passages or driving rock riffs.

Perfect for: Rock, alternative, new wave, post-punk, shoegaze, and any player seeking classic analog chorus with genuine vintage vibe.
