🎸 Elevate your tone—where vintage grit meets futuristic pitch wizardry.
The MXR Poly Blue Octave (M306) is a versatile analog octave pedal combining four separate octave divisions with independent level controls, polyphonic and monophonic pitch shifting modes, and a signature fuzz inspired by the MXR Blue Box. It features modulation effects reminiscent of Leslie and Phase 90, all controllable via expression pedal or tap switch. Built for tone explorers, it delivers rich, dynamic octave textures in a rugged, true bypass design.

Pedal excepcional
Um pedal bastante versátil, aflora a criatividade de quem usa. O fuzz então, é perfeito! Parece que tem um gate junto, pois elimina ruídos. Demorou um pouco para ser enviado, mas não muito. Enfim, melhor aquisição do ano, sem sombra de dúvida.
