It is a lovely thing when musicians come together to help a noble cause. This month, a group of female musicians and artists alike are teaming up with an online marketplace to give back. To help support the Girls Rock Camp Alliance, female musicians have partnered up with Reverb according to Pitchfork. Reverb is an online gear marketplace that allows musicians buy and sell used, vintage and new music gear. Some of the musicians who have teamed up with the online marketplace are Hayley Williams of Paramore, Lady Gaga, Sharon Van Etten, and many more. They will donate gear memorabilia for an auction that will launch this Thursday, May 10th.

The auction will include autographed memorabilia and music from Dolly Parton, Laura Jane Grace, Fergie, Reba McEntire, Lydia Loveless, Marian Hill, and Charli XCX. A few other musicians such as Sarah Lipstate, Melissa Etheridge, Wye Oak’s Jenn Wasner, Speedy Ortiz frontwoman Sad13, Evanescence, Ana Popovic, Sadie Dupuis, Tal Wilkenfeld, and Amanda Shires are parting with microphones, guitar pedals that they have used on stage and in the studio as well as signed vinyl. Among the other items that will be up for sale are Lady Gaga‘s digital delay guitar pedal that she used during her Joanne tour, Williams is parting with several of her microphones.  Parton is donating a few pieces of autographed merchandise, and Kate Pierson of the B-52’s is donating a Line 6 Varian 700 guitar used on stage by her bandmate Keith Strickland.  For a complete list of participating artists and the rest of the items being sold in the auction, check out Reverb.
