Pedal of Doom is the signature pedal developed by Ashdown for Geezer Butler, historical bassist of Black Sabbath.
Equipped with a transformer isolated Di output, with two switchable equalizers.
Dual VU meters designed to ensure the bass signal is balanced at the input and output of the signal path.
Using the input meter allows you to drive the equalizer to the desired level based on the instrument's output.
The output meter ensures that the return signal to the amplifier is the same as the input signal, to avoid unwanted gain jumps, or conversely to ensure gain boost when needed.
