Blended from circuit-archetype lineage, dynamic feel, tone-signal overlap and tone-vector distance — the tone vector itself is derived from editorial description text, not a measured acoustic signal, so this reflects how similarly the catalog copy describes the two, not a lab measurement.

The Ashdown Geezer Butler Pedal of Doom is a dual-channel bass distortion and preamp pedal designed in collaboration with Black Sabbath bassist Geezer Butler over 18 months. It features two independently switchable EQ stages, a 5-band active EQ, transformer-isolated DI output, and runs at 9V or 18V for adjustable headroom. The Clean channel delivers warm, vintage tube-amp-like character at low gain, while the Doom channel pushes into aggressive saturation and fuzz-laden territory. It suits doom metal, stoner rock, and classic heavy rock bass tones. Build quality is fortress-like with a 1.6mm steel enclosure. Best used as a bass preamp or DI unit as well as a tone-shaping drive, particularly for players wanting warm vintage saturation without sacrificing low-end presence.
The Ashdown James LoMenzo Mega Drive is a bass drive pedal designed with Megadeth bassist James LoMenzo, debuted at NAMM 2023 as an evolution of the Ashdown HyperDrive. It features sweepable highpass and lowpass filters for targeting specific frequency bands, a drive blend knob to mix clean and driven signals, adjustable input gain, and a VU meter for visual input monitoring. The circuit delivers a wide gain range from warm deep harmonic overdrive to bright cutting distortion, with full-spectrum frequency shaping rather than the HyperDrive mid-only approach. Suited for heavy rock and metal bass playing, it preserves low-end fundamental clarity while adding harmonic aggression on top. Used by James LoMenzo live with Megadeth as his primary bass drive.
