The QWS (Quad Waveshaper) is based on a well known, classic design. The original purpose of the module was to turn sawtooth waves to sine waves, using an LM3900 quad norton op-amp. The QWS uses all the available op-amps from the chip, also, there are link pads on the board, so with a switch and some wiring, you can link all four waveshapers temporarly together. Please note, this is a really dense board with a lot of parts and a lot of wiring - not recommended as beginner project!
