Over the summer, metal pioneers Black Sabbath reunited for one final concert to celebrate their years together and unknown at the time, it would become a goodbye to former lead singer Ozzy Osbourne.

Bass player Geezer Butler is selling some of his equipment that was used during the rehearsals leading up to the Back to the Beginning performance on July 5.

There are 15 signed Head of Doom amps up for sale; the made-to-order cabinets are also available separately via Ashdown UK.  The signed amps come with a certificate of authenticity.

The equipment is currently on display at Ashdown’s Reverb Shop and on October 14 at 10am CDT the amps officially go on sale.

Ashdown is also offering made-to-order speaker cabinets that are replicas of those used by Geezer on stage – The 2×15″ and 2×12″ cabinets, dubbed the COD-212-8 and COD-215-300 watts RMS at 8 Ohms and a custom medal grill screen-printed with Geezer’s artwork.
