These are honestly my favorite tuners. It was my first tuner, and I still have one on my test bench. Super accurate, easy to use. Really nice for intonation and precision guitar setups. This one has some wear, and some tape holding the rubber case together, but is still going strong. I used to run this on top of a dual rectifier lol. Works on batteries or power supply, has a signal through, but I'd recommend using it on a splitter.
