Mount Eerie’s Phil Elverum is selling an extremely rare Chamberlin Rhythmate Model 40, which he says is the “first drum machine in history.” (Léon Theremin’s Rhythmicon technically came first.) Only a very limited number of the tape loop drum machines were ever made. In the product listing on Reverb, Elverum explains that he inherited the instrument from his late great uncle Bill Lowman, who was an amateur musician and a fisherman by trade.

He notes that the machine was used on “countless albums recorded at Dub Narcotic in Olympia” for various artists including the Microphones, Mirah, Mount Eerie, the Blow, and more. Elverum also brought it on the road with him for live shows. The Chamberlin Rhythmate is going for $9,500. Watch a demo of him using it below.

In the listing, Elverum also mentions that he remembers a guitar tech offering to buy it from him for “Neil Young’s studio.” “Apparently he’d been looking for one. I said no thanks because I was in the middle of a tour and needed it,” Elverum writes. “Maybe he wants it still?” Elverum has additionally reached out to Kanye West on Twitter offering to sell the machine to him. “People keep telling me that you might want to buy the special drum machine I have for sale,” Elverum writes. “It is available. Peace.” Find the post below.

In March, Elverum shared his latest Mount Eerie album, Now Only. Read Pitchfork’s feature “Death Is Real: Mount Eerie’s Phil Elverum Copes With Unspeakable Tragedy.”
