For sale is a Vertex Effects Steel String Supreme (SSS) Double Preamp in excellent, fully functional condition.

This is the ultimate "D-style" clean machine, bringing the legendary, hyper-responsive tone of a real Steel String Singer amplifier directly to your pedalboard.

I purchased this unit as a pristine demo/open-box item directly from Sweetwater. It has been meticulously cared for, thoroughly tested, and tracks perfectly across all control parameters with only minor cosmetic signs of light use.

Unlike a standard overdrive, this dual-channel preamp acts as an entirely separate amplifier pipeline. It packs two independent channels, giving you massive flexibility. You can use it as an always-on master tone shaper to inject incredible glassiness, fat low-end authority, and touch-sensitive midrange punch into your rig, or configure the secondary channel as a dedicated lead boost that slices cleanly through any complex mix layout.

This listing comes complete with the original pedal, factory box, and manual. It will be safely and securely packaged for transit.
