Source Audio Vertigo Tremolo
The Blackcap is the harmonic take on OBNE's Whitecap tremolo. The Blackcap retains the analog tremolo side of the original and takes the highly functional digital tap side into the realm of harmonic tremolo. Where before it turned your volume up and down, now it crossfades between your highs and lows. Mixed in parallel or series with the amplitude modulating tremolo, it's pretty flippin neat.
Excellent condition, with box, ships fast and safe
