The TRIPLE WAVESHAPER is a non-linear wave modifier which can transform a sawtooth wave into a sin wave. This module incorporates three independent waveshapers which are useful for modifying synthesizer waveforms or for processing signals from preamped instruments.
Of course, it's uses go far beyond the use of the description above. By using each section in series you can add folds to the wave, each section adding a fold to the applied waveform. To get the best results of this action would be to use a sine wave as the source.
Plug an audio frequency sawtooth wave into the in jack on the top section. Monitor the output while turning the knob to fully clockwise. Adjust the appropriate trim pot until the output level is approximately that of the input. Repeat this process for all three sections.
