This is an excellent tuner. It’s far more accurate than clip on tuners, and you have a couple great option. You can run it so your sound doesn’t cut out while you tune, and it has an optional buffer that improves the sound of equipment that already sounds great. The display is super easy to see on stage, and you can easily change the setting for different instruments. I primarily use it to tune a EBMM Stingray Special 5HH, and it nails that B string every time. The display LEDs look cool too. They’re super bright.
