ANN ARBOR, MI -- Ann Arbor Public Schools and Biddergy.com are partnering to auction more than 500 of the school’s musical instruments.

The district is auctioning off the instruments because it “plans to update the equipment,” Natalie Roe, Biddergy.com director of marketing, said. Auctions are 8 a.m. to 8 p.m. March 11-12, online at Biddergy.com.

District voters approved a $33 million bond in 2015, and some of these funds are being spent on new instruments, Andrew Cluley, AAPS director of communications, wrote in an email.

“In November 2017, the board of education approved the purchase of instruments for nearly $2 million to serve as replacements, and to provide additional instruments to meet student needs,” Cluley said.

The instrument auction has two phases. Phase one is March 11, with trumpets, trombones, flutes, clarinets, saxophones, French horns and more. Phase two, March 12, will feature drums, guitars, cellos and violins.

Instrument stands, amplifiers, keyboards and xylophones are also available on Thursday.

All bidding starts at $5. Instruments are sold as-is. Photos of the instruments are available online, in addition to information on possible flaws, such as small scratches.

“The instruments in the current auction are those that still had some value, but were in fair or poor condition,” Cluley said.

Seven days after the auction, buyers can purchase items left behind at 1919 E. Kilgore Service Road in Kalamazoo.. Relocation of the musical instruments to Biddergy.com’s Northville location, 17000 Northville Road, Suite 300, also is available.
