Product Details
✓CLASSIC DISTORTION & FUZZ HYBRID: All-analog design blends fuzz and distortion for thick, saturated, aggressive tone. From tight crunch to raw roaring fuzz. First distortion pedal for guitarists—compact yet solid, great sound for home practice and small gigs
✓FAT & MOSFET TOGGLE — TWO INDEPENDENT VOICINGS: FAT adds thick low-end for heavy riffs and full solos. MOSFET switches clipping diodes for softer, smoother vintage sound; MOSFET off uses silicon clipping for brighter, more aggressive modern edge. Difference is most noticeable at higher DISTORTION settings
✓3-KNOB CONTROL — DISTORTION, FILTER & VOLUME: DISTORTION sweeps from edge-of-breakup grit to saturated fuzz (start ~9 o’clock for crunch, past noon for aggressive metal). FILTER rolls off highs clockwise for darker tone, counter-clockwise for brighter cut. VOLUME from unity gain to amp-pushing boost
✓SOCKETED OP-AMP FOR CUSTOMIZATION: Socketed OP07DP chip can be swapped for other popular op-amps to fine-tune gain structure, compression, and harmonics. Players describe the JOYO version as more responsive to op-amp changes, with audible differences
✓JOYO QUALITY & SUPPORT — Solid metal chassis. Dual power: 9V battery or 9V DC adapter (center negative). Rated current: 20mA. Use regulated isolated supply and avoid daisy-chaining for quietest performance. In the Box: 1 x Pedal, 1 x User Manual (No power adapter or battery included)
