I've been playing classical guitar as a hobby for 40 years. When I first started learning, I used a tuning fork, like many people in the past, without an electronic tuner. About 20 years later, when electronic tuners began to become widely available, I started using one myself. Tuning a classical guitar is so sensitive that even after tuning with an electronic tuner, I had to fine-tune it by ear.
Since then, I've used countless tuners over the years. I think I've owned at least four Korg tuners. I've lost them all, broken them, given them away, or thrown them away.
One day, I met a friend who had an older Petersen tuner. I was intrigued by it and bought it on Amazon. It was a clip-on HD model. The strobe display was a bit distracting at first, but I quickly got used to it, and I found it to be more precise than any other tuner I'd ever owned. Other tuners have a high tolerance, so I had to tune them with a tuner and then fine-tune them by ear. However, the Peterson tuner gave me a slightly more precise location than my ears could.
I used this tuner sparingly, but after a while, I noticed that its battery drained very quickly. Battery drain can be caused by a variety of factors, including my habits and storage, so I solved the problem by carrying multiple CR2032 batteries.
About two years later, the tuner began to flicker, and the screen would go blank during tuning. I searched online for various reviews, but I couldn't find any mention of this issue. The tuner would turn on, the screen would display, and I could adjust the settings, but I couldn't tune it.
Even though it had been over two years since I purchased it, I filed a Peterson support ticket to address the issue. I received a response a few days later, offering to send me a new tuner. I live in Korea, so it took about 20 days for the tuner Peterson sent me to receive.
I received the same Clip Strobo HD model as before, but with a square battery cover. I've always had trouble finding the right spot for the battery cover every time I change the batteries, and it seems I'm not the only one who has experienced this. I think it's a great upgrade.
I enjoy mounting it on my guitar and seeing the tuner's brightly lit strobe display. I no longer have to pull out my smartphone's tuning app every time I play, and I can now play with complete confidence in the tuner's tuning results.
I'd like to express my gratitude to John Norris of Peterson Tuners for his helpful advice and assistance.
