We all know that to work on your time and tempo, a good metronome is kind of a key piece of gear to have in your bag. When working out your parts, it will ensure that you're learning them in the proper tempo, too. I prefer a classic wind-up mechanical one like this to the grating synthetic "beep" of one of those cheap electronic ones - and this one never runs out of batteries, because it doesn't use 'em!
The precision mechanical clockworks are made in Germany, and built into a very clean-looking ruby-colored plastic case. It comes complete with a plastic cover that protects the arm from being damaged in your gig bag, purse or coat pocket.
This model sizes out at about 6 1/2 inches tall, making it a good compromise between the Super-mini, and the Tabletop models we carry. It's small enough to easily fit into a gig bag, but big enough to not get lost in there. Best of both worlds!
This metronome is 100% mechanical; it winds up and requires no batteries. It is capable of supplying accurate timing from 40-208 BPM. Instructions included. Dimensions: 6.5"H x 3"W x 2.5"D
TL;DR: Highly accurate, highly portable, super cool metronome for players on the go.
