Very recently, my friend gave me a tour of his guitar repair workshop. Sitting on his workbench, he had a Peterson Strobo HD which he uses to intonate a variety of guitars. Afterwards, he explained how incredibly accurate his Peterson was. The following week I finally purchased one. With my give collection of 4/5/6 basses and a classical guitar, I needed a great tuner - more so for recording and intonating when I do setups. The optional metronome feature is also a bonus.
In conclusion, I’ve never heard my classical guitar and 6 string bass sound so perfectly in tune. If you’re in the market for a tuner with incredible accuracy, whether it be lap steel or a banjo, this tuner literally covers it all. Highly recommended!
