Experience the legendary high-gain tone that redefined rock guitar with the Synergy Soldano SLO 2-Channel Preamp Module, available now at Haggerty’s Music. Born from Mike Soldano’s groundbreaking Super Lead Overdrive design, this module delivers the unmistakable voice that shaped everything from ‘80s hard rock to modern high-gain precision.

Faithfully designed by Mike Soldano himself, this all-tube preamp module captures the thick, harmonically rich distortion, tight low end, and singing sustain that made the original SLO-100 a benchmark for boutique amplification. With two footswitchable channels, players can move seamlessly from punchy, articulate crunch tones to soaring, fluid lead sounds. Each channel features its own gain and volume controls, while a shared three-band EQ allows for intuitive tone shaping across both voices.

Built for the Synergy modular system, the SLO module offers authentic tube performance in a compact, flexible format — no modeling, no compromises. Whether you're chasing classic hard rock tones, modern metal aggression, or expressive lead work with endless sustain, this module delivers the unmistakable Soldano character with the convenience and versatility today’s players demand.
