The Preference of Owning Your Tuner OVER Licensing Tuning Software
You don't really need to think about it too long. Should you go for a software emulator? You don't actually OWN the software if you go that route, you are simply licensing it; and you need to provide your own hardware as well as continue to purchase upgrades as your hardware ages and operating systems change. you might feel a bit sexier when you pull out your laptop or tablet, but you know they have a built-in obsolecence, are fragile devices with batteries that don't last and take a long time to charge. you can beat all these problems by buying your own Accu-tuner.Why ownership is better

Amazing Customers for 35 years
When Al Sanderson came out with the first version of our tuning device 35 years ago it was the first time anyone had figured out EXACTLY the formula for the rules of inharmonicity and how it could be applied to helping piano tuners in the real world. The formula has withstood the test of time.
No other ETD comes close
Try as they might, our competitors simply have not been able to improve upon the simplicity and accuracy of an Accu-Tuner. Whether using hardware or software solutions, they might get close, but why would "close" be good enough for a professional like you when you can have the ultimate accuracy of an Accu-Tuner?
unlike most companies who want to charge you for support beyond their waranty period, Inventronics is always there, free of charge to help you get the most from your Accu-Tuner. We can answer questions and provide seasoned advice. Need a repair, battery or software update? Our technicians will get your device working quickly at a reasonable cost. Our Accu-Tuner IV includes free software updates!
Unparalleled Accuracy allows multiple pianos to be tuned with identical results. Variation in volume level of partials or external noise will not change the tuning results. Don’t believe competitors’ claims that rules of inharmonicity should be rewritten to agree with their measurements.Read More
SimplE To Use
Sharp or flat is indicated with a rotating light pattern to an unequivocal resolution of ±0.05 cents. For inharmonicity measurements, the Accu-Tuner is superior to any other tuning instrument. Competitive units are misled by the volume of partials, decipher false beats, averaging their sum, which compromises the results.Read More
