I had a few versions of SFT before. My favorite one is previous, without a switch. But this one sounds nice too.
Sometimes I feel, like with my Telecaster I get not too much gain in stones mode, and too much in stoner. But overall it is good. A bit mid-focused, with loose low end. Stacks nice with Treble booster and fuzz.
What disappointed me, is that quality a bit off lately. On my pedal knobs are not the right one. Too small to cover shaft properly. Also, enclosure was not polished properly, so graphics looks pretty poor. Not a deal breaker, but I had 15+ Catalinbread pedals before, and non of them had quality issues. Also, for €200+ you could expect, that every aspect would be taking into account.
