Built with a compact chassic, four-knob layout of speed, depth, fx level and tone, and three-way mode switch for toggling between an enormous tri-chorus and swirly vibrato, the TC Electronic Gravy Tri-Chorus & Vibrato brings two solid effects together in one package. Expansive in their ranges, the two modes are also complemented by a TonePrint function which allows direct downloading from the TC Electronic website of new modes and features for added value. Whether you're looking for something new in the way of your chorus or are interested in finally checking out the brand, this pedal is a great entry into the world of TC Electronic.
