The Coriolis Effect is a phenomenon in classical mechanics where a trajectory becomes altered due to a rotating frame of reference. The Catalinbread Coriolis Effect has three main parameters to change the equations of motion for your guitar signal. Turning down the Velocity and Acceleration controls drags your playing into the heart of a black hole, redshifting your tone into a lower pitch and filtering out the high frequencies. The Hold button will instantly pull you into the black hole stopping time completely. Plug in and explore where humanity has never shredded before! In short: Think of the Coriolis Effect as a sustainer, wah, filter, pitch shifter, and harmonizer rolled into oneóthe sonic possibilities are endless! Controls ï Position: This parameter controls the dry/wet mix with a full wet on clockwise and full dry on counterclockwise. ï Acceleration: This parameter is a 2-pole low pass filter. ï Velocity: This parameter adjusts the pitch of the wet signal. ï Hold: Pressing this button stops any new sampling and loops the current sample. Other features ï Expression pedal Input. ï Internal bypass mode switch (True Bypass or Buffered Bypass). ï Internal expression pedal polarity switch. ï Internal trimmer pot to adjust gain level. ï Hand-built in Portland, Oregon, USA.
