Revol Effects is a Japanese guitar effects pedal brand launched by Kyoritsu Corporation, a Tokyo-based musical instrument distributor. The line is built around compact, full-metal-shell enclosures with true-bypass switching, and the company markets the pedals as high cost-performance alternatives to boutique stompboxes, using proprietary parts supply and in-house production.

The lineup covers a broad range of standard effect categories, including distortion and overdrive pedals such as the EMD-01 Metal Distortion, the EFD-01 Black Drive amplifier emulator/overdrive, the EOD-01 Navy Blue Overdrive, and the EDS-03 Triple D high-gain distortion. Modulation and ambience options include the ECO-01 Clam Blue Chorus, the ERV-01 ThreeVERB reverb, and the EWA-01 Auto Wah. Utility products include the ENR-01 single-knob noise reduction pedal and the RT1 automatic tuner for guitar and ukulele.

The brand is distributed internationally through retailers such as Amazon, Reverb, and eBay, and maintains a relatively low profile outside Japan compared to larger domestic pedal makers.
