Detail 01
Harmonic tremolo
It crossfades between high and low frequencies rather than raising and lowering volume.

Independent shopping perspective
Blackcap pairs analog amplitude-modulating tremolo with a harmonic tremolo section on its digital tap side. Rather than simply moving overall volume up and down, the harmonic side crossfades between high and low frequencies. The two tremolo approaches can be combined in parallel or series, giving you a choice in how they interact. It runs from standard 9VDC center-negative power and comes in a black enclosure sized 3.27 by 1.93 by 4.8 inches.
