Used Demonfx SSS Steel String Supreme

The Demonfx SSS Steel String Supreme is an analog preamp and overdrive pedal designed to recreate the sound of one of the rarest amplifiers in history: the Dumble Steel String Singer.

It is a direct homage to the Vertex Steel String Supreme, which is famous for delivering the "glassy" and "clean-to-mean" tones associated with players like Stevie Ray Vaughan.

The "Steel String Singer" Tone

The SSS is not a typical heavy distortion pedal. Instead, it is designed to add "bloom" and harmonic thickness to a clean signal.

• The "SRV" Sound: It is optimized for that specific Texas Blues character—thick, clear, and highly percussive.
• Preamp Utility: Because it is a "preamp-in-a-box," many players use it at the end of their drive chain or even as an "always-on" base to make a standard clean amp feel and react like a high-end boutique head.
• Dynamic Range: It is noted for its extreme touch sensitivity; it stays remarkably clean until you really "dig in" with your pick, which then triggers a smooth, tubelike breakup.
