Independent shopping perspective
The Korena take
Ashdown's Geezer Butler Pedal of Doom combines two switchable four-band EQ voices with a dedicated Doom overdrive section. Set two tonal foundations, then change between them by footswitch as a part moves from supportive low end to a more mid-focused sound. Input and output VU meters help manage level changes, while the transformer-isolated XLR DI offers a direct output for stage or studio routing. Output, Doom, and Doom-volume controls shape the final signal path.
Strong match
Who this is for
- Moving between two prepared EQ settings during a song using the EQ 1/2 footswitch.
- Sending a transformer-isolated XLR direct signal to stage or studio routing.
- Monitoring input and output levels with separate VU meters while engaging overdrive.
Consider the trade-offs
When to look elsewhere
- Use without an external power supply, because 9-18V DC power is sold separately.
