Blended from circuit-archetype lineage, dynamic feel, tone-signal overlap and tone-vector distance — the tone vector itself is derived from editorial description text, not a measured acoustic signal, so this reflects how similarly the catalog copy describes the two, not a lab measurement.

The Cusack Music Tap-A-Whirl V4 is the fourth and most advanced generation of the Tap-A-Whirl analog tremolo pedal, featuring 24 preset tremolo waveforms, a digital preset system integrated from the Resound reverb for saving and recalling tremolo presets, and a fully analog audio path. Tap tempo for live BPM synchronization. Boutique American construction from Cusack Music. The most feature-complete version of the Tap-A-Whirl in the lineup.
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.
