Geezer Butler signature bass amp head. Hand built in the UK Custom Shop, the Head of Doom was designed around Geezer Butler’s (Black Sabbath) very requirements.

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 and 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.
