Modern tone with a vintage soul. Boss's FZ-1W is a fuzz pedal that honors tradition but revels in the possibilities of the now. The FZ-1W follows your dynamics and volume knob fluctuations to deliver the true synergistic playing experience of a vintage fuzz pedal. What you do is what you hear. But you won't hear tone-sapping variables like age, battery type, and temperature changing the effects' sound and performance. Two modes offer a wide range of tonal possibilities. Vintage mode gives you classic fuzz tones and a wider expressive range, so you can ride the volume knob as you navigate your emotions. If you're looking for a focused, phatter fuzz, then dial up modern mode. The wider gain range offers more drive so when you push the fuzz knob past three o'clock, you're rewarded with a sweet, singing sustain for your most expressive solos. But it gets better. Use the FZ-1W as a boost before your amp or other gain pedals, and you might never put your guitar down again. Higher gain, lower noise, deep tone shaping control, reactive playability, and rock-solid dependability. Good fuzz is worth waiting for.Boss FZ-1W Features:Premium Waza Craft pedal for the ultimate BOSS tone experienceRedefined fuzz sounds that combine classic tone and response with modern versatility and stability, realized through BOSS Waza innovationVintage mode delivers a retro fuzz experience with aggressive tone, dynamic touch response, and extreme sensitivity to input volumeModern mode provides a fatter sound and more mid focus to suit a wider range of music stylesPowerful Tone knob provides deep sound-shaping control tuned for each modeConsistent sound and reliable performance with silicon transistor circuitryHigh-quality buffer for clean and clear tone when bypassedBOSS five-year warrantyBoss FZ-1W Specifications:Nominal Input Level: -20 dBuInput Impedance1 M ohms (Effect Off)22 k ohms (Effect On)Nominal Output Leve: l-20 dBuOutput Impedance: 1 k ohmsRecommended Load Impedance: 10 k ohms or greaterControlsPedal switchMode switchFUZZ knobTONE knobLEVEL knobIndicator: CHECK indicator (Serves also as battery check indicator)ConnectorsINPUT jack: 1/4-inch phone typeOUTPUT jack: 1/4-inch phone typeDC IN jackPower SupplyAlkaline battery (9 V, 6LR61 or 6LF22) or Carbon-zinc battery (9 V, 6F22)AC adaptor (PSA series: sold separately)Current Draw: 16 mAExpected battery life under continuous useAlkaline: Approx. 33 hoursCarbon: Approx. 14 hours*These figures will vary depending on the actual conditions of use.AccessoriesLeaflet (“USING THE UNIT SAFELY,” “IMPORTANT NOTES,” and “Information”)Alkaline battery (9 V, 6LR61 or 6LF22)Options (sold separately): AC adaptor: PSA seriesSIZE AND WEIGHTWidth73 mm2-7/8 inchesDepth129 mm5-1/8 inchesHeight59 mm2-3/8 inchesWeight (including battery)430 g1 lb Boss FZ-1W Waza Craft Fuzz Effect Pedal.
