WORKING CONDITION: Very Good. This Blue Box operates as it should, with both lower octaves sounding strong at extreme settings.

PHYSICAL CONDITION: Very Good. There is a tiny chip in the paint on the chassis, but otherwise, the pedal is in excellent condition.

INVENTORY #58757

BRAND: MXR 

MODEL: M103 Blue Box

FUNCTION: Guitar Effects Pedal

PRODUCT DESCRIPTION: This listing is for an MXR M103 Blue Box Script Logo Octave Fuzz Guitar Effects Pedal. The MXR M103 Blue Box Octave Fuzz is a classic analog effects pedal known for its aggressive, gated fuzz combined with an unpredictable sub-octave that drops the signal two octaves down. It is famously used for the solo in Led Zeppelin's "Fool in the Rain" and is prized for its "8-bit" glitchy, synth-like character.

SPECS:

• Two-Octave Sub-Octave: Unlike standard octave pedals that drop one octave, the Blue Box duplicates your signal two octaves down for deep, subterranean tones.
• Simple Controls: Features just two knobs: Output (sets total gain) and Blend (mixes the dry fuzz signal with the sub-octave).
• Monophonic Tracking: Best suited for single-note lines, as it can become chaotic or "glitchy" when playing chords.
• Power & Design: Housed in a rugged metal chassis, it can be powered by a 9V battery or a 9V DC adapter.

ACCESSORIES INCLUDED: This item comes as seen in photos and does not include any accessories.
