The Korg TM-50 is the perfect size and has plenty of nice features. The only down side is the metronome's lack of volume.
Shoreline was great. Super fast and friendly!
I've owned another model of the Korg tuner, gave it away, and now have this handy tuner/metronome. It's a great tool to have, particularly if you plug it into a chain that has a mute switch contained in it. And, of course it has that metronome built in, in case you don't have perfect mental tempo ticking. I tend to speed things up a bit, so this prevents the "runaway train" during rehearsal. Great price and fast shipping as always from Shoreline.
This is a great little piece of equipment. Very handy to keep around and practice with since it has a metronome built in. I love that the metronome has a tap temp, which is super handy to tap a beat in and then make sure you're on beat the entire time. The Korg Beat Boy has a little drum machine built in as well, which is kind of cool. Personally, I find myself gravitating towards Snark tuners for their simplicity and the fact that I can tune with them in a loud room. I also use a TC Polytune 2 when I'm on stage. But if you want something simple with a metronome built it, this isn't a bad choice.
