Dynamic Flanger/Phaser Effects Pedal

Dynamic Flanger Phaser Pedal
with Random Stepped Filter
Hardcore Frank Zappa fans know that to recreate some of the great mans most classic tones is, nigh on impossible without the use of some of his weird and wonderful effects pedals. Even then, getting your hands on some of the effects he used, is another challenge!

Until now! Fortunately, the guys at Keeley have thankfully developed the ‘Bubble Tron’ – a wonderful combination of a ‘Phaser’, ‘Random Synth Filter’ and ‘Dynamic Flanger’ (heavily inspired by the ‘MixMix DynaFlanger’ used by Zappa himself). Sporting a set of user-friendly controls, along with 3 modes of operation, Keeley’s ‘Bubble Tron’ helps to deliver some of Zappa’s most recognisable guitar sounds!

Amazing Features • A Dynamic Flanger Phaser and Random Synth Filter with three modes of operation
• Inspired by the incredible MicMix DynaFlanger, as used by none other than Frank Zappa
• Internal DIP switches (under back plate) allow you to change between Bank 1 or 2 of sounds
• Responds to the severity of your pick attack
• Hand made in the USA

2 Phaser Types


Dynamic FlangerTaking large inspiration from Zappa’s favoured ‘MicMix DynaFlanger’, the ‘Bubble Tron comes in and out dependent on your pick attack or envelope setting, as opposed to running continuously. This flanger mode also gives the choice between positive and negative feedback thanks to the ‘FDBK’ control, unleashing a whole new avenue of sounds to experiment with.

'DynaMo' PhaseThe ‘Bubble Tron’s circuit is separated into two separate phasers, one utilises a user-defined LFO, whilst the other uses a true dynamic phaser, this too relies upon your picking dynamics. You can choose to use both phasers alongside each other, or, just bring the ‘Rate Control’ to zero, and enjoy the dynamic phaser alone.

Synth Filter


retro synth and keys soundsThe Synth Filter is the sole non-dynamic mode inside the ‘Bubble Tron’, but that doesn’t mean it’s unusable of lacking in dynamics. Make sure to take full advantage of the ‘Shape’ parameter to determine the voicing and the behaviour of the pedal, or just tweak the ‘Sensitivity’ control for a collection of retro synth and keys sounds!

Superior ConstructionAt the centre of the ‘Bubble Tron’ is a hand-wired circuit board, and is the result of decades upon decades of effects-engineering know-how from some of the best engineers in the business. Attention to detail and precision is what the guys at Keeley do well, and have done well for so long. Add a Keeley pedal to your board and you’re sure to feel, and HEAR the difference.
