Used Keeley BubbleTron Effect Pedal

Used Keeley BubbleTron in great condition—an expressive analog-style envelope filter/auto-wah pedal that adds funky quack, vowel-like sweeps, and touch-sensitive dynamics to guitar or bass. Features intuitive controls for sensitivity, filter range, and effect level, with multiple filter/response modes for everything from subtle motion to bold synthy tones. Standard 1/4" input/output, rugged stompbox build, and 9V DC power for easy pedalboard integration.
