This amplifier is in very good condition with no damage and minor cosmetic wear. 3 of the EQ slider tips are missing but the sliders themselves are working perfectly with no issues. The amp has been fully tested and is 100% working, the Ashdown footswitch is included as well. The amplifier comes mounted in a very solid tweed rack mount case.

From Ashdown

Introducing the Ashdown 'Head of Doom' Geezer Butler Signature Bass Amp Head. Hand built in the UK Custom Shop, the Head of Doom was designed around Geezer Butlers very requirements.

The Ashdown and Geezer Butler story began three years ago after extensive talks with Geezer's long standing tech, Terry Welty. Black Sabbath's 'The End' farewell tour was approaching and Geezer was extremely specific about his bass sound for the band's departing tour. Ashdown designed a rig for Geezer to leave a bold statement with, encapsulating a music career spanning 50 years into one sound to remember the almighty Black Sabbath by.

The Head of Doom is for bass players who seek classic, driven bass tones with phenomenal power. Stripped back, the Head of Doom is built on Ashdown's flagship ABM range; offering tried and tested tone and rock-solid reliability.
