Planet Waves Mini Headstock Tuner - Highly precise tuner for a wide range of instruments
These tuners are great for banjo, by making it small it clips on to the back of the banjo peghead and you can barely see it at all from the front. It blends in with the peghead and is very small. The light is easy to see behind the peghead and the tuner does not need to be removed to fit in the case.
Having a tuner sticking off your banjo neck while you're playing is frankly kind of lame, especially if you leave it on with an annoying green light flashing. I have started using these and the tuner function works really well too, and I can see it without glasses. It fits in the case without removing it if you want too, great idea. thanks, Ross
