From Lenny Cleans to Texas Flood Leads!

When it comes to SRV-style glassy clean and fat lead tones, the Vertex Effects Steel String Supreme SRV is the only tone shaper you'll need!

The Steel String Supreme is based on serial #001 of a legendary six-figure tube amp.

Players like SRV, Eric Johnson, and John Mayer have all sung the praises of this rare 100W 6L6 blues machine.

Just like the amp it's named after, the Steel String Supreme is characterized by a fat, clean, compressed sound.

The Steel String Supreme is guaranteed to put a smile on your face: marinating your signal in tube-like 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 Steel String Supreme is the next best thing to owning a real-deal SSS!

Sweet, sweet Dumble tones!

At lower gain settings, the SSS SRV makes a highly versatile fat boost (with an active EQ section to dial-in that D-style midrange).

Above 1:00, the Steel String Supreme sweetens your signal with vine-ripened drive characteristics matured in the California sun.

Wide open, this pedal packs enough juicy gain to take you well into overdrive territory!

Reintroducing the Slight Return Version.

Reviving the popular Slight Return Version model was a no brainer!

The original 2018 Slight Return Version routinely fetches upwards of $400 on the used market with its cult following!

Vertex is now re-releasing the SRV in their new, multi-channel Supreme format.

The Steel String Supreme SRV model takes all the great aspects of the original 2018 model and adds all the magic of the added Supreme channel.

You get more than double the features, two independent channels, and added toggle switches for tone shaping.
