Blackcap

The Blackcap delivers harmonic tremolo with the warm, vintage character of classic amp tremolos. The harmonic variation creates richer modulation than simple volume-based tremolo.

Harmonic tremolo splits the signal into low and high frequencies, modulating them out of phase. The result is warmer and more three-dimensional than standard tremolo. The effect recreates the feel of vintage Fender brownface and blackface tremolo.

Rate and depth controls shape the modulation. The voicing stays warm at all settings. The effect suits players wanting authentic vintage tremolo character.
