Combining an octave fuzz with a ring modulator built side-by-side for individual or simultaneous operation all on the foundation of analog circuitry, the Blackout Effectors Crystal Dagger makes an fuzzed-out, octave'd, phased effect not for the faint of heart. Capable of metallic ring, Octavia-like fuzz, and sweeping phase, all of which can interact with one another for truly experimental effects, this pedal is perfect for post-hardcore, experimental, or art rock.
