Guitar Tuner and Bass Tuner for Windows

Guitar Tuner and Bass Tuner are the first desktop Windows apps that I wrote. I don’t recall how long ago, but it was certainly more than a decade.

They’re super-simple apps that let you sound notes to tune your guitar or bass to. They only support standard tuning and use the default MIDI device for sound output, which usually means the “Windows MIDI Mapper”, a built-in sound synthesizer that’s been part of the OS for ages.

For nearly ten years I had them available for download on, and they had more than 100k downloads in total. Two years ago I open-sourced them, but didn’t really mention it anywhere.

I updated them both today, adding two notes to Guitar Tuner to support 8-string guitars and making improvements to the installers.

Both the source code and the installers are available on GitHub under the MIT license.
