Used Keeley BUBBLE TRON Effect Pedal

Used Keeley BUBBLE TRON effect pedal in great condition, delivering classic envelope filter, phaser, and funky auto-wah textures with the clarity and punch Keeley is known for. Simple, gig-ready controls let you dial in sensitivity, depth, and rate for everything from subtle vowel-like sweeps to bold, synthy pulses. Built in a rugged stompbox enclosure and designed for standard 9V DC pedalboard power, it’s an inspiring tone-shaper for guitar or bass.
