Trap Door Electronics Active Acid analog low-pass filter pedal.

Great Pedal! Bought for recent pedal board build. Decided to go a different direction. Excellent Condition.

If you are looking to inject rich, mind-bending synth textures into your guitar, bass, synthesizer, or studio tracks, this is the ultimate tool. Built around the legendary 4-pole SSM filter circuit inspired by the vintage Prophet-5 synthesizer, the Active Acid delivers everything from subtle tone shaping and warm overdrive to wild, squelchy, resonance-dripping soundscapes.
