Tuners & Metronomes by Korg and Boss

This Dr. Beat does everything!  First of all, gives chromatic tones in several octaves  which you can play along with (as drone for whatever key you're playing in.)  The metronome is the 'must have one' type that can give accents or louder beats wherever you like plus hundreds of different combinations.  Read more here about the Dr. Beat: (owner's personal comments.)

One of my favorite little tuners that easily fits into the palm of your hand.  You can clip it on the tip of the bridge and check your tuning in just a few seconds. (I like to use this one just before the orchestra tunes together.)  Gives you more confidence that you are perfectly in tune and without feeling too hurried at tuning time without having to ask to tune. Goes into your front pocket.

Another good tuner/metronome and for the money! Has LCD tuner with built-in metronome, chromatic tuning, tome function sounds a tone when pitch is correct, plays pitch tones and metronome has 7 rhythms.  Nice Boss LCD screen as well.

Korg TM-40 is a nice pocket size tuner/metronome and has input for electric bass or pickup cable. Also plays tones and nice LCD screen.
