Manufacturer's Description

Based on a Legendary Texas Bluesman’s Clean Amp Tone

When it comes to Texas-style glassy clean and fat lead tones, the Vertex Effects Steel String SSS (Slight Return Version) Mini — based on serial #001 of a legendary six-figure Steel String Singer Amplifier — may be one of the BEST ways to impart D-style clean tone to your favorite amplifier.

Whether you're front-ending a stage amp with the SSS Slight Return 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 Slight Return 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 Slight Return 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:

However, now in 2022, we're re-releasing the Steel String (Slight Return Version) in a single channel Mini version separately from our multi-channel "Supreme" format. The Steel String SSS Slight Return Mini model takes all the great aspects of the original 2018 model and puts it in a smaller, pedalboard friendly format, in addition to EQ voicing controls with the “Rock” and “Jazz” toggle switch.

D-Style Cleans With Some Texas Flair

With gain settings below 1:00, the SSS Slight Return 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 Slight Return Version 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 pedal engaged — though, if you're anything like us Texas Blues fanatics, it's pretty much a nonissue, since you'll never want to turn this thing off. The Steel String Slight Return Mini is assembled in California and comes in a rugged steel housing with authentic D-style appointments of the Steel String Singer:
