BubbleTron

The Keeley BubbleTron is a multi-effect modulation pedal designed to provide dynamic flanger, phaser, and stepped filter effects. This Keeley effects pedal offers three selectable modes. The dynamic flanger and phaser sections respond to playing intensity, triggering modulation based on pick attack, while the stepped filter section offers random bandpass filtering inspired by vintage synths. The BubbleTron includes user-adjustable controls for mode selection, rate, and feedback polarity (positive or negative) on the flanger. The phaser section features both an LFO-controlled and a dynamic mode. True bypass switching is standard. **Features:** - Dynamic flanger and phaser with pick-attack-sensitive modulation - Three selectable effect modes: flanger, phaser, and stepped random filter - Stepped filter includes vintage synth-style bandpass shaping - Flanger mode allows switching between positive and negative feedback - User-adjustable LFO rate and modulation depth controls - True bypass analog signal path Category search terms: modulation pedal, flanger pedal, phaser pedal, stepped filter effects pedal, Keeley effects pedal, true bypass
