I recently found out about some pretty cool guitar tech for you players out there. The Roadie tuner can be pre-programmed for various tunings. It fits over the turning gear of your stringed instrument (doesn't have to be a guitar!) and automatically tunes the string to that frequency once it's plucked. The company is releasing a new and improved version for bass guitars and other instruments. It's already fully funded but you can preorder it here.
But if you have money to spend but not $80 on a guitar tuner, why not give me considerably less money on my Patreon? You can get private content, playlists, and if you're a big enough spender, your very own podcast or post!
