Quick Sine - Sine Wave Generator

A tiny, reliable, no-frills analog sine wave generator tuned for audio work.

When I discovered that there were’t any inexpensive analog bench-top sine wave generators out there that reliably produced good sinusoids, I decided to build one for myself. I had previously tried a few of the cheap Amazon / Aliexpress signal generators only to discover unusably noisy signals or sine waves that were way too triangular.

The Quick Sine, while more limited in functions than these other devices, reliably produces a lovely sine wave without significant distortion. It's designed around a fairly simple Wien bridge oscillator network and tuned to offer you a selection of 9 different frequencies within the audio range. It will output a constant line level signal.
