Single most important rule in musicianship…
Play in tune, and in time.
Here’s a product line that will help you do BOTH.
Meet the Snark.
Many models under $15. C’mon dude, that’s less than a 1/4 tank of gas for the car, or 3 mocha chocolate, low fat, soy, shaken and stirred latte’s.
There are many other brands releasing these headstock tuners. Invest in thyself!
If you can’t play in tune and in time, it’s time to change that.
