Reverb is hosting an online auction that features items donated by Loretta Lynn, Kacey Musgraves, Dolly Parton, Lauren Alaina, Little Big Town, Reba McEntire, Wynonna, Faith Hill, Cassadee Pope, Margo Price, Lindsay Ell and more. Proceeds will benefit 10 Girls Rock camps in the U.S. and Europe, with the goal of fostering music education for female youth.

The Girls Rock Reverb Charity Auction opens on May 21 and runs through May 28, offering bidders the chance to purchase more than 50 items, including autographed memorabilia, instruments, equipment, concert tickets, clothing and more. Other artists who have donated items include Stevie Nicks, Joan Jett, Indigo Girls, Annie Lennox, Fergie, Kelly Clarkson, Pink, Shakira and more.

“We as women and trailblazers have a responsibility to encourage young women to rise up,” says Loretta Lynn. “No longer can we be looked over. Those days are over, friends.”

Last year’s auction raised more than $20,000 for the Girls Rock Camp Alliance.

Check out a few auction items below, including a guitar signed by Faith Hill,  a pair of cowboy boots signed by Reba and a pedal signed by Lindsay Ell. Happy bidding.
