Product Description
- The Legendary Frank Zappa The late Frank Zappa was an American musician with a career that spanned more than thirty years in the 70s and 80s. His music played an influential part in jazz fusion due to his unique sound and lyrics on controversial issues such as politics structures and movements often humorous. Due to his unique sound and iconic status Keeley decided to capture that same sound and make it available to Zappa fans. This pedal cleverly explores some of those same sounds from the past. Bubbletron The Bubbletron takes its inspiration from the MicMix DynaFlanger which was famously used by Frank Zappa to achieve his iconic sound from the 70s and 80s which featured a dynamic flanger effect to reach envelope based flanging in his solos. A dynamic flanger starts and stops based on your pick attack or envelope and similarly to this the Bubbletron uses your playing to start and stop the flanger. Control Options Unlike other flanger pedals on the market the Bubbletron cycles its effect only when you play and works in dynamic with your pick attack and strength. It also offers both positive and negative feedback with its FDBK Rate control delivering a choice of sounds from a hollow tone to a thicker smoother sound. The Sensitivity control allows you to set how sensitive you want the flange effect to be from a delicate strum to heavy fingerpicking. The Depth control allows you to control how deep you want the flanging effect to be. DynaMoPhase The Phase section of the Bubble Tron features two phaser effects. One has an LFO that you set the speed of with the Rate Control and the other is a true Dynamic Phaser. It starts and stops based on your pick attack and allows options for adjusting the Depth and Sensitivity delivering a very watery sound based on your guitar&rsquo
