Ashdown Head of Doom – Geezer Butler

GEEZER BUTLER SIGNATURE BASS AMP HEAD

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 Butler’s 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.

Versatile EQ
The Head of Doom features a sophisticated 9-band EQ, with familiar Bass, Middle & Treble controls and six sliders allowing precision cut and boost in the regions the standard controls can’t reach, providing a huge range of tonal variation and the tailring of the perfect tone.

The EQ can be switched in via footswitch taking the player from a flat fretless sound to their favourite EQ setting instantly.

Sub-Harmonic Doom
Once heard – never forgotten. The Sub-Harmonic generator adds an octave below the notes being played bringing fullness to any bass part. The Sub level is independently controllable, thickening the sound and providing more DOOM to your tone as required.

Sub Harmonics are also controllable via footswitch.
Please see the illustration below, this feature was added so Geezer could power his 12 on stage cabinets ensuring the quality of signal was maintained.
