WORKING CONDITION: Excellent. All pots function as they should. This is a great fuzz that can handle chords without getting mushy or folding in on itself.

PHYSICAL CONDITION: Very Good. The hand-painted finish shows some signs of use but all of the pots, jacks, and the switch are in very good condition. 

INVENTORY #58755

BRAND: Blackbox

MODEL: Ultraviolet Fuzz v1

FUNCTION: Guitar Effects Pedal

PRODUCT DESCRIPTION: This listing is for a Blackbox Ultraviolet Fuzz v1 Big Box Guitar Effects Pedal. The Blackbox Ultraviolet is a rare, boutique quad-channel analog fuzz pedal known for its complex tone-shaping abilities and unique parallel circuit design. The "big box" version typically refers to the early, hand-painted original units in their standard large enclosure.

SPECS:

• 9V Battery Only - No Power Supply Jack
• The Ultraviolet is distinguished by its ability to split a guitar signal into four separate parallel fuzz channels. This design prevents the "mush" often associated with stacking high-gain effects.
• Parallel Processing: It functions essentially as four fuzz boxes and three differently voiced wah-style filters running in parallel.
• Filter Sections: Three of the four channels pass through active filter sections (Low, Mid, and High Freq), while one channel remains unfiltered to maintain the original signal's core.
• Tone Range: The pedal can produce everything from warm, rich distortion to an extremely dense "wall of sound" fuzz.
• Fuzz & Mix: The Fuzz knob controls the overall saturation, while the Mix knob allows you to blend the filtered and unfiltered channels.
• Frequency Knobs: Dedicated Low Freq, Mid Freq, and Hi Freq knobs allow you to tune feedback harmonics and shape the EQ of each parallel channel.
• Volume: A master volume control sets the final output level.
