Frequently Asked Questions

The Poly Blue's polyphonic tracking is significantly improved, handling multiple notes cleanly where older models struggled. It’s still not perfect for super complex voicings, but a huge step up.
It's inspired by classic fuzz tones but isn't a direct clone. It’s got its own distinct character—a blend of warmth and grit that sits well with the octave effect.
Absolutely! While marketed for guitar, the Poly Blue works very well with bass, offering some unique sub-octave textures. Just be mindful of the low-end boominess with the SUB-2 setting.
