Here's the info about this little rare classic from the seller...
GIBSON MAESTRO RHYTHM QUEEN MRQ-1 Electric Drum Machine Synth Percussion Tempo
This is a very nice vintage MRQ-1 Maestro "Rhythm Queen" drum machine. It is in perfect working condition, and looks great for its age, only has minor wear on some corners and edges, no rips or tears. The sound that comes out of this unit is excellent. Great for playing guitar over. I particularly like the GO-GO button! Adjustment between the Balance and Tempo with 8 separate rhythm models, makes this a very versatile machine. Excellent for studio use, has 1/4" output to amp on back panel, or built-in speaker on side.
