GEEZER BUTLER Is Selling The Bass Amp Heads He Used At BLACK SABBATH’s Final Show

Black Sabbath bassist Geezer Butler is giving fans a chance to own a piece of history that also happens to sound awesome. Butler and Ashdown have teamed up to sell 15 Head Of Doom amps that are hand-signed by Geezer himself and used during Black Sabbath‘s final shows in July 2025.

Ashdown will also create made-to-order speaker cabinets that help fellow musicians replicate Geezer‘s sound if you’re not into spending a shit ton of money. The 2×15″ and 2×12″ cabinets, dubbed the COD-212-8 and COD-215-8, will be handcrafted in the UK to the same specs as those at the final show, allowing musicians to get Geezer‘s sound via 300 watts RMS at 8 Ohms and a custom medal grill screen-printed with Geezer‘s artwork. Check it out here on Reverb.

“The end of an era. The sound of a legend,” wrote Reverb. “Ashdown UK have just announced that they will be selling 15 Head Of Doom amp heads used by Geezer Butler at Black Sabbath‘s final shows in July 2025. Available exclusively on Reverb, each amp is hand-signed by Geezer, complete with a certificate of authenticity from Ashdown’s Managing Director, Dan Gooday.
