Good sine wave tool

Good simple tone oscillator, can double as a tuning source for musical instruments. A4 = 440. Presets can be created for stringed instruments.

best one i could find!

best one i could find, simple and does exactly what it needs to and has the ability to go much louder than the others. but can you make it go below 20 hz? like down to 5 or something?
