The Walpurgis Iommic Overdrive Preamp combines two legendary circuits into one unparalleled Sabbath Worship device.
Designed in collaboration with Nick Williams of Dunwich Amplification.
Featuring an internal 36V of headroom for authentic tube-like tone and response, the Walpurgis is a JFET-based emulation of the preamp section of a late ‘60s Laney Supergroup amplifier with the Worship Knob controlling the wet/dry blend of a modified Dallas Rangemaster boost.
Harness Tony Iommi’s iconic guitar tones from the ’60s, ’70s, and beyond with the turn of a single knob.
The Walpurgis can be used as an overdrive pedal into the front end of your amplifier or turn up the internal master volume trim pot to boost the output and run it as a preamp into your effects return or dedicated power amp.
Controls
