Description
Some pedals chase a sound. The SFT chases a feeling — that thick, sagging, all-tube growl old Ampeg heads gave bassists back when amps were built to move air, not just make noise. Catalinbread set out to nail that specific breakup, the kind that shows up on those loose, heavy “Ya-Yas” era recordings, and landed on a drive circuit that works whether you’re chasing classic rock warmth or shoving your signal into modern drop-tuned territory.
What makes the SFT worth a spot on your board is how it EQs. Instead of a basic bass/treble knob setup, you get a Baxandall-style tone stack — the same shaping philosophy used in real tube amps — so you can carve mids and dial in low-end without the drive turning to mud. Push the Stones/Stoner switch and the gain character shifts, giving you a second flavor of breakup without needing a second pedal.
Because it was built bass-first, the SFT doesn’t fall apart when you dig in low. Low B strings stay defined, drive stacks cleanly with your clean tone if you blend it right, and the overdrive holds together at gig volume instead of collapsing into flub. It happens to work great on guitar too, but this one was engineered with low end as the priority — which is why it belongs in a bass player’s hands.
- Ampeg-inspired tube amp voicing in pedal form
- Baxandall EQ for musical, amp-like tone shaping
- Stones/Stoner switch for two distinct drive characters
- Equally capable on bass or guitar
