"Imagine a weekly jam session, you and 40 or 50 friends, open bar, taped all night on a tube-driven reel-to-reel, a great time for all, except you rarely get a drummer to these events. A good friend of mine was in this exact situation. Solution? Especially for an hours-long jam to a single tune? A solid, well-made, good-sounding drum machine, of course! Enter the Korg KR55, an early drum synth with exactly what my friend was looking for - 10 drum voices, 48 pre-set rhythms, 16 intro/fills, easy to hook up to a guitar amp, easy to operate. This is an analog design from the early 80's, and was a staple for years in studios during the period. Comes with original box and manual. When it was last tested about 2 years ago, everything worked perfectly, so the pots and switches may need to be cleaned. Best wishes!"
