Does It Doom Walpurgis Vol2 Sabbathic Overdrive

The Walpurgis Vol2 takes the foundation of the original JFET-based emulation of a late ’60s Laney Supergroup amplifier and plunges even deeper into the void.  Now, we’ve fully unlocked the Supergroup EQ, volume, and gain—previously hidden behind the wall of sleep—and fused them with a fully adjustable, modified Rangemaster boost, inspired by the legendary Dunwich Rangeblaster design.

Featuring an internal 36V of headroom for authentic tube-like tone and response, the Walpurgis Vol2 is a JFET based emulation of the preamp section of a late ‘60s Laney Supergroup amplifier with the Ritual knob controlling the level of a modified Rangemaster boost.

Step into Tony and Geezer’s legendary Sabbathic guitar and bass tones from the ’60s, ’70s, and beyond.  Use the input toggle to the right for those iconic Iommi Supergroup ‘Bass Input’ tones, and dial up the Ritual and Range knobs to blend in the Rangemaster boost for that signature Iommic overdrive.  Flip it left and zero out the Ritual knob for the classic Geezer ‘Treble Input’ bass sound, or center it for a high-gain, jumped-channel configuration reminiscent of Matt Pike’s Supergroup setup on Sleep’s The Sciences.

The Walpurgis Vol2 can be used as an overdrive pedal into the front end of your amplifier or as a dedicated preamp into your effects return or standalone power amp.

Controls

Bass: Adjusts the low-frequency response of the Supergroup preamp.
Mid: Adjusts the mid-frequency response of the Supergroup preamp.
Treb: Adjusts the high-frequency response of the Supergroup preamp.
Pres: Adjusts the upper high-frequency response of the Supergroup preamp.
Vol: Adjusts the overall output level of the pedal.
Gain: Adjusts the level of gain applied to the signal in the Supergroup preamp emulation.
Ritual: Adjusts the wet / dry blend of the modified Rangemaster boost.  Set this control at 0 to remove the Rangemaster boost from the circuit entirely.
Range: Controls the boosted frequency range of the modified Rangemaster.  Set this control at 0 for a biting treble boost; roll it up for a thicker, full range boost.
Input Toggle: Input setting for the Supergroup preamp.  Three adjustable levels of gain: Bass Input (right position), Treble Input (left position), Jumped Input (center position)

Power

Use only a standard 9v DC power supply with a 2.1mm negative-center barrel.  An isolated power supply is recommended.  Power supply not included.
