PRELOVED VERTEX EFFECTS Steel String

PRELOVED Vertex Effects Steel String — Crystal-Clear Boost to Smooth Overdrive

The Vertex Steel String Clean Drive is a highly musical tone-shaper designed to capture the feel and response of the iconic Dumble Steel String Singer in a compact pedal. It’s built to cover a wide range—from fat clean boost and compression-style thickening through to crystal-clear overdrive and mid-focused EQ shaping, making it a killer “always-on” foundation pedal.

Vertex even calls out those famous, glassy clean/edge-of-breakup tones associated with records like “Texas Flood,” “Venus Isle,” and “Continuum” when used into a clean amp platform.
