Description
Based on Steve Ray’s Legendary Dumble Clean Tone
When it comes to SRV-style glassy clean and fat lead tones, the Vertex Effects Steel String SSS SRV (Slight Return Version) Mini — based on serial #001 of a legendary six-figure Dumble Steel String Singer — may be one of the BEST ways to impart D-style clean tone to your favorite amplifier.  
The Dumble amplifier we used to voice the Steel String series pedal, SSS #001:

Whether you're front-ending a stage amp with the SSS SRV Mini’s expanded midrange control via the “Filter” knob or glassier highs and fatter lows via the Rock/Jazz switch, this pedal is guaranteed to put a smile on your face. Just like the amp it's named after, the Steel String SSS SRV Mini is characterized by a fat and glassy tones sound that absolutely marinates signals in tubelike harmonics as you ramp up the gain with plenty of available top end "glass" and a little more low-end "snap" compared to the original Steel String MKII. From subtle fattening and clean compression to full-on overdrive, the SSS SRV Mini edition is the next best thing to having the real-deal SSS in your rig!

Bringing Back A Cult Classic
Reviving the popular "Slight Return Version" model was a no brainer!  The original Slight Return Version (during the Steel String MKI era in 2018) routinely fetches upwards of $400 on the used market with its cult following:

D-Style Cleans With Some Texas Flair
With gain settings below 1:00, the SSS SRV Mini makes a highly versatile fat boost, with an active midrange “FILTER” EQ section to dial in that D-style midrange shaping your instrument demands. Above 1:00, the SRV sweetens your signal with vine-ripened drive characteristics matured in the Texas sun. Wide open, this pedal packs enough juicy gain to take you well into overdrive territory. All the while, true bypass operation preserves your dry signal whenever you don't have the SRV engaged — though, if you're anything like us Stevie Ray fanatics, it's pretty much a nonissue, since you'll never want to turn this thing off. The SRV is assembled in California and comes in a rugged steel housing with authentic D-style appointments of the Dumble Steel String Singer:
