Parabola

The Caroline Guitar Company Parabola is a solid-state tremolo inspired by vintage Schaller TR-68/TR-316 pedals. The transistor-generated waveform changes shape with the depth control for organic, living modulation.

Two modes expand versatility: AM mode provides classic amplitude modulation tremolo, while FM mode creates frequency-dependent filtered modulation that's subtle and shimmering. The +12dB preamp can add clean gain or drive.

The Havoc momentary footswitch triggers intense tremolo flurries or choppy bursts depending on settings. Volume, Speed, Depth, and Drive controls shape the effect. The Parabola captures any tremolo tone from 50s rockabilly to modern shoegaze.
