The SFT was painstaking crafted by Catalinbread to recreate that elusive not-clean yet not-dirty sound made famous by The Rolling Stones use of Ampeg guitar amps in the late 60s. The SFT is one of Catalinbread's Foundation Overdrives – pedals can give you big, cranked up amp response at non-cranked volumes. To use it as intended, you’ll want your amp set to a relatively clean, flat response. In fact, the new SFT pedal responds particularly well to fuzzes, boosts, and overdrivers.

In addition to Gain, Volume, Treble, and Bass controls, the SFT features 2 distinct modes: STONES and STONER.

STONES mode gives you just the right ammount of drive you need to replicate those classic late 60s "Get Yer Ya-Ya’s Out!" type of tones. Not too distorted, yet brimming with attitude. STONER mode unleashes full-throttle fuzz. The Volume and Tone controls on your guitar can be used to tame STONER mode and still have room to unleash the beast when it’s time.
