The Chase Bliss Audio Gravitas Analog Tremolo continues Chase Bliss' reputation for building some of the most innovative tone shapers around. This pedal can churn out just about any historic style of tremolo you can imagine from simple volume modulation and harmonic tremolo, to far more out-there warbling styles. Add in a bevy of detailed, digital controls over the analog signal path plus an additional mod shape circuit, and you end up with one of the more advance tremolo pedals ever produced.
