Although Lofi is in vogue these days, to consider Caroline Guitar's Somersault low fidelity is an injustice. It's pitch may waver, there may not be a sine wave in sight but this is all perfectly accomplished. Nothing sounds "broken" here or is reminiscent of an effect brought back by nostalgia.  

      It is a perfect vibrato. It can place you on a sonic wave in triangle mode or create a unique tremolo, one that actually changes pitch within a square wave.

      While the digital chip sets the delayed wet signal, the initial gain stage, dry signal, LFO, control set and output mixing stage are entirely analog.

• Offset Controls the time difference between the modulated and dry signals
• Speed Sets the rate of the oscillation sweep
• Depth Sets the intensity of the wave on the modulation line
• Mix The MIX control can go from completely dry (counterclockwise) to completelywet (clockwise)
• Wave Toggle Selects either triangle or square waves
• Tone Toggle Alows for full range sound or high-end cut on the wet signal
• Havoc Removes the Speed control from the equation , maxing the rate on demand.
