Keeley’s Bubble Tron Dynamic Flanger Phaser is one of the more “out there” pedals in the Keeley range. For tone-chasing experimental players, the Bubble Tron can provide you with some Neo-Vintage sounds that never were.
You can discover a world of wacky effects thank to the Bubble Tron’s 3 modes – Filter, Phase and Flange.
Deriving from the MicMix DynaFlanger, the Flange mode reacts to your pick attack, so you can start and stop the effect with your playing. The Sensitivity control sets the threshold, so that it reacts the way you want depending on how hard you play. You can switch between negative and positive flange feedback with the Depth, so if you want a subtle and hollow flanger or a crazy swirling jet-sound, both are possible. If you're an ambient player, you can use this effect to add interesting modulated layers to your music.
The Phase mode is essentially 2 phasers in 1. An LFO has been added to one of these and you can set your preferred speed with the Rate, from a gentle slow movement to an intense flutter. The other is a pure dynamic phaser, and both of these react to your pick attack like in the Flange mode. The phaser tone can be adjusted if you play around with the Depth and Sensitivity knobs, producing a range of liquid-y sounds to spruce up your guitar tone.
The Filter mode isn’t dynamic, meaning you can set this up the way you want without your playing affecting the response. The Shape knob allows you to control the ramps, creating some random filtered noises to surprise your audience with. You can shape the vintage-style bandpass filter with the Sensitivity control, so you can achieve some amazing keyboard-inspired sounds. If you play funk, this envelope-style filter makes notes pop to get your playing heard.
"The homie Robert Keeley coming through with another super unique entry to his catalog! How do you feel about Filters? How do you feel about Phase? How about Flange? How about all three-in-one? You a Frank Zappa fan? The Bubble Tron Dynamic Flanger Phase is the all-in-one pedal you need! If you’re feeling adventurous, one of the modes on the Bubble Tron is designed to be random. But I promise you, you will get some of the coolest sounds ever, from it." - Pedals And Effects
