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.
