Your picture is of a Lesmann Accordion Organ - I own one purchased new in 1968
I have lots of information about this instrument:
- a man with the last name of Searles and his partner Ralph Studemann combined the ends of their last names and came up with the "Lesmann" name - I knew both men and spent a lot of time in their "factory" since my instrument had some electronic problems when new - these instruments were sold at the "West Allis (WI) Music Center" which was owned by Ralph Studemann - most of their instruments (which consisted in the electronic organ built into a standard accordion) were built into Morbidoni (or Morbadoni) (Italian, imported) accordions which were high quality instruments - under a contract with LoDuca Brothers in Milwaukee some of their instruments were put into LoDuca accordians (I played in bands with the LoDuca brothers and I would argue that the quality of the LoDuca accordions were not up to the Morbadoni standard)
The six pin connector provides all the power to the instrument and ties in to the Lesmann amplifier which, I believe, is essential for the electronic operation of this instrument. The "sliding" bar referred to in responses simply closes the sound passages and MAY reduce the volume of the wind accordion but is especially used to keep dust out of the inside of the instrument if it is stored outside its case. The chrome buttons on the instrument control the wind accordion sounds. The white switches control the built in electronic organ. The round black knobs control the volume of the wind accordion through the amplifier (that would be standard on any amplified accordion whether or not it had an organ built in). The organ volume is completely controlled by a foot petal. Your pictured instrument only has a organ built in for the keyboard. Mine also has an organ for the bass (button) part of the accordion and so I also have two volume knobs to control the volume of the organ in the button section relative to the keyboard.
In the 60's there were several manufacturers of similar instruments. Very popular was the CORDOVOX which was somewhat difficult to maintain since it's cord (from the accordion to the amplifier) had a wire for each note on the keyboard. Replacing or fixing that cord was almost impossible or, at least, incredibly expensive. Another manufacturer was the ACCORGON which could be plugged into any amplifier with a simple cord (like a guitar cord) and even had the ability to be plugged in and separated from the amplifier (a "wi-fi" or "bluetooth" type of connection) which allowed the player to "stroll" away from the amplifier with full access to its sound. Neither of those instruments included the quality of the Morbidoni accordion which was the basis of the Lesmann instrument.
I would be happy to discuss the Lesmann Accordion with anyone looking for information but I am especially interested in finding out WHERE CAN I GO TO GET SERVICE ON THE ELECTRONIC PART OF THIS INSTRUMENT!!! After 45 plus years the electronics are not all responding properly (even though few listening to me play would know it).
Anyone have an idea? Contact me anytime:
