Similarity
citedBlended from circuit-archetype lineage, dynamic feel, tone-signal overlap and tone-vector distance — the tone vector itself is derived from editorial description text, not a measured acoustic signal, so this reflects how similarly the catalog copy describes the two, not a lab measurement. Shown only within a gear class, and only where there's enough evidence to be meaningful.

Description

This is the Dunlop Billy Gibbons Siete Santos Octavio Fuzz, a Jim Dunlop signature pedal endorsed by Billy F. Gibbons of ZZ Top (the display name 'Sieste Santos' is a typo of the product's real name, 'Siete Santos'). It combines the Octavio fuzz circuit, which layers an upper-octave harmonic overlay onto the fuzz signal, with a seven-slider graphic EQ spanning 100Hz to 6.4kHz with up to 18dB of cut or boost per band, letting players precisely shape the Octavio fuzz's frequency balance. The Octavio circuit produces a rich, singing fuzz with distinctive octave harmonics that are especially prominent on single notes played in higher neck positions. It suits blues-rock players wanting Gibbons-style Octavio fuzz with the added ability to dial in the exact EQ balance of the fuzz output, rather than a simple fixed-voice octave fuzz.

The MXR M267 Octavio Fuzz is a recreation of the Tycobrahe Octavia, the vintage octave fuzz used by Jimi Hendrix on Purple Haze and Fire, delivering the characteristic upper octave fuzz saturation that defined Hendrix's most experimental lead work. The Octavio produces an upper octave above the fundamental note, creating a complex, singing lead tone that became one of the most iconic sonic signatures in rock guitar history.
