Dunlop Billy Gibbons Siete Santos Octavio Fuzz
Dunlop · pedal
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.
