Linkin Park fans have a chance to collect around 200 pieces of gear used by the music group throughout its 17-year-long career.
A portion of the sales will be donated to Music for Relief, an Entertainment Industry Foundation (EIF) programme founded by the band in the wake of the 2004 Indian Ocean tsunami, Spin magazine reported.
The items to go under the gavel include the keytar featured in the "What I've Done" video to a theremin used by Mike Shinoda.
Other key pieces of equipment include the Amplivox S602M Megaphone LP's lead guitarist Brad Delson used on tour in 2011 and a sticker-covered road case.
Techno Empire's Reverb.com store will start selling the gear from tomorrow onwards.
"Throughout the last 13 years, Linkin Park fans have been incredibly generous supporters of Music for Relief, truly enabling our mission to help survivors and communities in the wake of natural disasters," Whitney Showler, EIF VP of operations, said in a statement.
