When it comes to Mayer-style compressed clean and lead tones, the Vertex Effects Steel String Supreme - based on serial #001 of a legendary six-figure tube amp - is the only tone shaper you'll need in your arsenal. Whether you're front-ending a stage amp with the SSS's expanded all-analog preamp, feeding a little Texas sugar into your modeling device, or even running straight into a cab IR, this pedal is guaranteed to put a smile on your face. Just like the amp it's named after, the Steel String Supreme is characterized by a fat, clean, compressed sound that absolutely marinates signals in tubelike harmonics as you ramp up the gain. The Supreme's active EQ and Bright/Deep + Rock/Jazz switches add new tone-shaping capabilities to this latest addition to the Steel String family. From subtle fattening and clean compression to full-on overdrive, the Vertex Effects Steel String Supreme is the next best thing to having a real-deal SSS in your rig.
