The TM-40 Metronome-Tuner tunes a variety of instruments from guitar to a bassoon. This Korg tuner has a plug-in for your guitar or bass which makes tuning your rock-out instrument easier. The tuner on the TM-40 can even pick up some of the softer sounds that a instrument can produce making it ideal for band directors and music lovers alike. If your instrument is stubborn, the TM-40 can be re-calibrated at the touch of a button to differ from the perfect 440. It also has a speaker that sounds out any note on the western scale so you can hear, not just see when your instrument is out of whack.
The TM-40 not only has a tuner, but also has a metronome that uses a digital needle that sways back and forth to show you the beat so you can see and hear it. The metronome can range from largo (40bpm) to presto (208bpm) and can be programed to have up to seven beats per measure. Overall I have found the TM-40 to be the best Metronome-Tuner out there for the price, but what really makes it special is that if you are extra clumsy (like me), the TM-40 has a three-year warranty so you know it is tough enough for any musician, whether you are a Punk rocker, or a beginner in your local school.
