The Old Blood Noise Blackcap is a versatile tremolo pedal which offers both harmonic and standard tremolo modes, as well as a "Shape" control that adjusts the waveform of the tremolo effect. The harmonic tremolo mode produces a more complex, modulated sound by splitting the signal into high and low frequencies and modulating them separately, while the standard tremolo mode produces a more traditional, rhythmic effect. There is no box included.

This Old Blood Noise Blackcap is in Excellent condition. There is mild surface level scratching, but this pedal is fully functional.
