"This is a quick demo of this very rare Chamberlin Model 25 Rhythmate Drum Machine that we have for sale. We do not know of any others like to this in existence. It is very small compared to the better known Chamberlin Model 30 Drum Machine. It was designed to hang off a organ bench. Amazing!"

"This video was shot by renowned synth and organ tech Ken Rich while he was restoring our Chamberlin Rhythmate Model 25 Drum Machine. Built in 1949, it may be one of the earliest made. It is truly a Drum "Machine". This video shows the internal workings of the tape loop. See our other demo video with the unit put back together."

"This listing is for an extremely rare CHAMBERLIN Rhythmate (model 25) tape loop drum machine. It is one of the first drum machines ever produced, made in 1949. This is a modular version that seems to have been made to hang on a piano or organ bench. Very little is known about it or if there are any others. It may have been a one-off. The internal workings are a marvel to behold with several feet of recorded drum loops winding around multiple pulleys. See video's...

It measures a tiny 8.5 inches tall, 4.5 inches wide and 6 inches deep!

ACCESSORIES - Includes the Reverse Hanger to mount on a organ bench. This item comes only as seen in photos, does not include any other accessories.
PHYSICAL CONDITION - Excellent. The paint on the reverse hanger scratched off in places and starting to oxidize. For it's age it's in great shape.
WORKING CONDITION - Very Good. We just got this little guy back from service from renowned tech Ken Rich (
In Ken's words "It's the most fascinating piece of gear I've ever had in my shop". This says a lot as Ken's shop has seen the utmost of coolest organs, electric pianos, synths and drum machines in the world. See the quick video below that Ken took of it's operation without the wood box covering its amazing internals."
