## Overview

The Ashdown Geezer Butler Head of Doom is a powerful 600-watt bass head featuring a tube preamp, versatile input options, and dual VU meters, designed for musicians who demand both performance and tonal richness.

## Description

The Head of Doom has a deadly power section rated at 600 Watts RMS with two Neutrik speakon outputs. The power section has a minimum load of 4 ohms. The slave input on the rear is designed to be fed by the transformer-isolated outputs if running multiple heads from one input source. More heads - more doom! From the top, the Head of Doom features a single instrument input linked to a passive/active selector switch. The passive input option (switch out) is high sensitivity and high impedance to suit the output from passive basses. Perhaps the most obvious feature on the Head of Doom is its twin set of VU meters - the first Ashdown amplifier head of its kind. Not only does the head look like a daemon on stage, the second VU meter allows for output level visual monitoring. Now bass players can find the sweet spot for their instrument via the familiar input level VU. From there the player can tweak their tone via an experienced 9-band EQ and use the shape control to further sculpt their tone, all the while monitoring the output level at the same time via the second VU. The Head of Doom is loaded with connectivity. A tuner output, line out, transparent FX loop and a line input for the connection of an external sampler or sound source. Output muting cuts the signal from the DI output but leaves the tuner output 'live', allowing the player to tune up in silence. A pair of Neutrik Jack/Speakon sockets with a minimum 4 ohm load provide flexible partnering options so that the Head Of Doom can be used to power a single 8 ohm cabinet, a pair of 8 ohm cabinets or a single 4 ohm cabinet. The ‘Doom’ control increases the current to the amp’s 12AX7 pre-amp valve stage, like voltage through an electric chair, resulting in the richest harmonic distortion designed specifically for bass guitar. Used in conjunction with the amps impressive EQ section, there isn’t much this amp can’t deliver. The Doom level control can be pre-set and kicked in and out via footswitch.
