Tick-tock. You either love it, or hate it...the metronome. If you are unfamiliar with this great practicing tool, it may take a few hours to get accustomed to it, but no doubt, your playing will excel once you master playing in time with a metronome.
The full-featured metronome included in Guitar Shed is one of the best of its kind. Its fully adjustable timing allows you to set the exact BPM (Beats Per Minute), choose an instrument from many samples, and set a variety of options.
There's even a flashing light to tell you when it hits beat-1 (The first count), which is extremely helpful when playing with odd-time signatures.
