I first used this tuner while on a very noisy tour with heavy metal bands, which made it very difficult to tune the acoustic guitars used during a portion of the band I worked for's set. The combination of a Peterson tuner and the Pitch Grabber saved the day!
Works just great with my iPad Pro. Great customer service too. I’ve used an old model 570 for almost 40 years and it still works, but this makes the Strobesoft app a better and more accurate tuner then anything else I’ve used
This works great with my smart phone. I'm using an Android tuning app called "A Tuner" which is free and extremely accurate. This clip is durable and the cord is made in such a way that it won't crack or break like my old one did. I'm sure I'll get many years of use out of this. Very happy with it.
