Prometheus SubDecay Filter FX Pedal

The Prometheus SubDecay Filter is like that espresso-fueled sound engineer you secretly admire — precise, a little obsessive, and always pushing the low end into territory you didn’t know was fun. If your bass rig feels like it’s missing a bit of character, this pedal isn’t here to apologise — it’s here to carve out space in the mix with attitude.

Think of it as a sculptor for your tone: sweepable peaks, resonant sweeps, and filter magic that can go from subtle warmth to “did that bass just learn to sing?”. It doesn’t just sit in the chain and look pretty — it interacts with what you’re already doing and makes it feel like it meant to be there.

Whether you’re dialling in a funky envelope sweep, hinting at a synth vibe, or just want to make your lows groove in ways your amp didn’t think possible, this pedal is that secret weapon that makes other bassists raise an eyebrow and go, “huh… nice choice.”

Why It’s Worth a Spot on Your Pedalboard

• Responsive filter sweep — from gentle warmth to squelchy resonance

• Musical interaction with your playing dynamics

• Versatile for styles from funk slap to ambient hammer-ons

• Compact but confident — doesn’t hog space, but demands attention
