Beautiful item purchased in June 2025. Purchase price: 15,400 yen Fuzz by BOSS's digital technology. Don't underestimate the digital aspect. This is an exceptionally well-made pedal. It produces a solid fuzz sound and is a very easy-to-use fuzz pedal. Personally, I prefer this over the FZ-1w. Used only in a room. Never stepped on with a foot. Includes box and other original accessories. Includes a replacement bottom plate and silver screws for easy installation on a pedalboard. The following is a quote: The FZ-5 faithfully models the characteristics of germanium transistors used in historical vintage fuzz pedals at the component level. You can switch between three different types of fuzz sounds with the knob. The F mode features a saturated low-E string sound, as well as a moderately mild distortion on the plain strings. The M mode perfectly reproduces the dirty sound of the earliest distortion models, and the O mode perfectly reproduces a unique sound that is like adding an octave above the original sound. The COSM technology models the fuzz sounds that colored the 1960s and 70s with their unique sounds. It faithfully reproduces three types of vintage sounds: FACE/MST FUZZ/OCTAVE FUZZ. FACE (F): A disc-shaped model that is indispensable for the psychedelic fuzz sounds of the late 1960s. It reproduces the fat sound using germanium transistor AC128. MST FUZZ (M): A model using germanium transistor 2N2614. It has a unique fuzz sound with emphasized high frequencies. OCTAVE FUZZ (O): A vintage fuzz that adds an octave above the original sound as the sound decays. The tonal changes due to input gain are also realistic.
