Pictured here is one of our PARABOLA test pieces: a solid state, transistor generated waveform tremolo. The oscillator is strongly influenced by the vintage Schaller TR-68/TR-316 â€œWest Germanyâ€ tremolo pedals that I fell in love with in the 1990s. They have a gorgeous analog waveform that actually changes shape with the depth control, and a feel that is unlike anything Iâ€™d ever played before or since.
Beyond a faithful approach to the transistor LFO, there are a host of improvements weâ€™ve made. The Parabolaâ€™s volume control has more than enough output to compensate for any perceived volume loss of the tremolo effect â€“ in fact, itâ€™s up to +12db of clean gain â€“ AND there is a gorgeous preamplifier drive stage based on the â€œinvaderâ€ preamp of our Kilobyte and MÃ©tÃ©ore pedals, so you can crank the gain and generate drive at any volume. You can think of the Parabola as an additional â€œtremolo channelâ€ for your setup.
The AM mode is the classic Schaller amplitude modulation, gorgeous and wobbly, like sloshing through deep puddles with your rain boots on. The â€œFMâ€ mode is a frequency dependent â€˜filteredâ€™ mode based on the depth control that manages to create a shimmering effect that gets out of the way of your playing. The Speed, Fast/Slow, and Depth ranges have been improved both from the (often incorrect) Schaller schematics people post online and the real deal vintage TR-68s we traced, and the Depth can be easily zeroâ€™d out to allow you to just use the gorgeous preamp and booster. And the Havoc â€œinvertsâ€ whichever speed range youâ€™ve chosen and opens up the depth control, so you can momentarily â€œjuiceâ€ or â€œdragâ€ the effect on demand.
