Joyo JF-307 Clean Glass - gitaareffect

Most overdrive pedals push your amp into distortion, but the JOYO JF-307 Clean Glass takes a different path—it recreates the pristine clean channel of a Fender Twin Reverb amplifier in a compact, pedalboard-friendly format. Instead of adding grit, it delivers glassy clarity, expanded headroom, and that unmistakable American clean tone. Whether you need a transparent foundation for your effects chain or a boost to make your clean sound shine, the Clean Glass is an essential tool for players who value purity and definition.

Highlights

• Authentic Fender Twin Reverb clean channel emulation
• Ironman Mini Series: ultra-compact aluminum alloy enclosure
• True bypass switching preserves your core tone
• Simple Volume, Drive, and Tone controls for instant shaping
• Low 20mA current draw – ideal for daisy-chained power supplies

In daily use

The Clean Glass excels as a tone enhancer and clean boost. Set the Drive low for a transparent volume lift or crank it slightly to add a touch of harmonic richness without losing clarity. The Tone knob lets you dial in just the right amount of top-end sparkle, while the Volume control ensures unity gain or a healthy boost for solos. Its true bypass design means your signal remains untouched when the pedal is off, and the bright LED indicator keeps you informed on dark stages. Powered by a standard 9V DC center-negative supply (not included), it integrates seamlessly into any existing pedalboard.
