Behold, an inverted exorcism of scorching sonic terrorism, as bones pound and sculpt torrid lands of sand.

Baghdad stands as tribute to Matt Pike’s early-era High on Fire guitar tone, capturing the searing power of the High Gain Channel from a Soldano SP77 preamp driving a bludgeoning Green Matamp GT120 amplifier.

Within the forgotten sun of Baghdad, a firestorm of sound blazes forth, its smoke swirling with scorpion-like incantations, birthing a feral Impaler…

Each vacuum tube gain stage of the SP77 High Gain Channel has been meticulously transformed into an op-amp gain stage, faithfully emulating its frequency and gain response. The preamp circuit boasts controls for Gain, Bass, Middle, Treble, and Presence, conjuring a savage symphony of tonal brutality.

The emulation of the Green Matamp GT120 circuit has been distilled to two essential controls: Drive and Depth. Drive infuses additional distortion and overdrive, while Depth shapes the frequency cutoff, a primal passage to the barbaric dominions of the otherworld.

Once again, we confront the vulgar vulture of Babylon, a sweltering spike that punctures the familiar head.

The combination of the GT120 controls, in harmony with the SP77 preamp section, unlocks a vast sonic palette, spanning from tight and percussive to a low-end heavy, almost fuzz-like response, as a single Volume control governs its merciless output.

This formidable circuit draws its power from an internally generated bipolar ±9V power supply, providing ample headroom and signal swing. Yet, it remains modest in its power requirements, as it only necessitates a standard center-negative +9V 100mA power supply.

Immersed in a desert-dwelling abyss, this device of doom emerges, wielding an ancient flail, casting shadows of terror and foreboding.

Within the realm of fetid ivory, timeless wails echo through eternity, veiling these hymns of secrecy that guard the haunted siege of history, forever etched in their spectral embrace.


Treble:  Adjusts the high-frequency response of the SP77 preamp.
Middle: Adjust the mid-frequency response of the SP77 preamp.
Bass: Adjusts the low-frequency response of the SP77 preamp.
Pres: Adjusts the upper high-frequency response of the SP77 preamp.
Volume: Adjusts the overall output level of the pedal.
Gain: Adjusts the level of gain applied to the signal in the SP77 preamp emulation.
Depth: Adjusts the frequency cutoff for a high-pass filter in the GT120 emulation.
Drive: Adds additional GT120 distortion and overdrive.  Set this control at 0 to remove the GT120 emulation from the circuit.


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.
