So the other day I bought myself a new tuner because I lost my old one. It's one of those with an inbuilt metronome. But it turned out to be completly retarded, first of all not being able to choose the right note, or just not working at all. Anyone had this problem before? It's a SupremE Metro-Tuner MT-30
try taking it back and get one like your old one maybe?
I have 2 tuners one is really good and always works. The other is one of those chord computer things with a tuner in it and it doesnt work worth a crap as a tuner. Some are just better than others. And the quality control of chinese electronics is pretty much nonexistant.
