I'm looking at amazon, and I'm not seeing the one I have, so I'll go and check later. Not that I'm an expert or anything, but when I bought it, my guitarist friend (Spacey) told me to get this one, it was the default one that everyone got, did the job, and was relatively cheap. I want to say it was a Yamaha, but I'm only seeing one Yamaha, and mine looks more like one of the Korg's, but cheaper. It's just got a simple little LCD display, tunes, and does nothing more (no metronome, no nothing).
