Old Blood Noise Endeavors Blackcap Harmonic Tremolo
Old Blood Noise Endeavors · pedal
The Old Blood Noise Endeavors Blackcap is a dual asynchronous harmonic tremolo combining a simple three-knob analog tremolo with a more complex digital harmonic tremolo in one pedal. The analog side offers classic amplitude tremolo with rate, depth, and volume, ranging from slow sways to fast chopping. The digital side is a tap-tempo harmonic tremolo that crossfades between highs and lows rather than just modulating volume, with five selectable waveforms including sine, triangle, square, saw, and reverse saw for lush swells and synthy pulses. A series/parallel toggle lets the two run into each other or side by side for complex, asynchronous choppy textures, with volume boost on each side, expression control, ramp mode, and relay bypass. It suits vintage, ambient, and experimental players wanting tremolo from classic to far beyond.
