Description:

Robert Keeley and his crew are fans of Zappa.  Rabid Fans.  This pedal explores some of the famous, but very hard to find sounds of the past.  Keeley Engineering has created another batch of Neo-Vintage effects that never were.  This time Keeley has made the Flanger and Phaser in dynamic with your pick attack and strength.  Then add the Random Stepped Filter with the new “M-Style Synth” bandpass  shaping feature, and you have a lead guitarist’s dream tool.  Shut up and play your effect pedal!  Yeah, you play this thing like an extension of your mind and fingers.

The Keeley Bubble Tron Dynamic Flanger Phaser and Random Synth Filter has three modes of operation.

The Flanger section of the pedal draws on inspiration from the MicMix DynaFlanger.  This incredible piece of gear was used by FZ to create many of the sounds in the late 70s to mid 80s  where a dynamic flanger was used to get envelope based flanging in his solos.  A dynamic flanger is one that starts and stops based on your pick attack or envelope.  The word envelope is used because if you were to measure the “weight” of your guitar signal and put it in a storage container (the “envelope” is an imaginary capacitor) it can then be used to control another part of the circuit.  The Bubble Tron uses your playing to start and stop the flanger.  Most flangers just cycle around and around and you can hear that swooshing in the background.  Not in this case, it only cycles as you play.  Many flangers offer only positive or negative feedback.  This one allows you to try either with the FDBK Control.  The negative feedback sounds more vocal like and hollow to my ears while the positive feedback is more conventional and has a thicker, smoother sound.  The Sensitivity Control allows you to set how delicately you want to play and have the flanger go fully crazy on you.  You can set for crazy silverback gorilla flange or easy flangin’ on Sunday morning.  The Depth Control is just that, how deep you want the flanging to be.

The DynaMoPhase section of the Bubble Tron is actually two phasers.  One has an LFO that you set the speed of with the Rate Control (while it’s depth is dynamically controlled) and the other is a true Dynamic Phaser.  It starts and stops based on your pick attack.  Again, you can set the Depth and and Sensitivity of this phaser to give you a very watery sound that is all based on your guitar’s signal.  You can turn off the standard phaser and just run it DynaPhase by turning the Rate Control off.

 

The only effect that isn’t dynamic is the Filter Section of the Bubble Tron Dynamic Flanger Phaser.  With the Filter you can control the different ramps or random nature of the pedal with the Shape Control.  The very exciting part of this pedal is the Sensitivity Control which is actual like a vintage synth style bandpass filter control.  It shapes the bandpass filter on the filter and gives you some incredible keyboard like sounds.

 

One very nice side effect of dynamic based effects is that they don’t produce the constant, swooshing sound of LFO based effects.

If you’re a lead guitar player that likes to explore and has never had the kind of expression or dynamics from your sound effects that you have in your mind, this is for you.  If you are a sound-experimentalist, this is for you!  The sounds are nearly endless in that your input shapes what the effect will do.

The Bubble Tron Dynamic Flanger Phaser is made in Edmond, Oklahoma by rabid Zappa fans.  It was Designed and Engineered by Aaron Tackett, Craighton Hale and Robert Keeley.

      No show but stays on
      Size: Medium, Color: (014) Halo Gray / Halo Gray / Castlerock
      I wear these socks daily. They truly don’t show with my workout shoes or with hey dudes. But the best thing about them is that they actually stay on your foot. I work out hard and I don’t ever have to pull them up. I do wish they were just a little bit thicker than they are, but they are definitely a product I will buy again.

      Worth the investment
      Size: 1 Panel, Size: 1 Panel
      I had to order this in an emergency. To put it in brief words, I live in a two level studio unit. My bedroom TV fell backwards off the bureau accidentally and down the stairs to its demise. Putting this together was no problem, instructions were thorough and easy. It came with several bars that connected together smoothly and an Allen key for the brackets and screws for the feet. I did one less horizontal bar on top and bottom so it could fit, which was great because with all of them on it was too long. However I ran into the difficulty of the horizontal bars popping out of the brackets during the last stages, but eventually got it done. I was also looking for a specific type of divider where I could adjust the feet so I could tuck it in between the dresser and banister. Glad I made this purchase.

      You Get What You Pay For! A Piece Of Junk!
      Size: 1 Panel
      Flimsy and a piece of junk. Don’t waste your money. Assembly is a pain because it is so flimsy. Divider is thin. You can see right through it. Very wobbly.

      Instructions are useless
      Size: 1 Panel
      The instructions are poorly written and not very helpful. The divider itself is easy to assemble, and honestly, it would’ve been quicker if I had skipped the directions altogether. Once put together, though, it works as intended.

      This was the best
      Size: 1 Panel
      This divider is great for creating a little privacy or separating a small area without taking up much space. The fabric is thick enough to block visual clutter, and the frame is lightweight but stable once it’s opened. It folds flat for storage, which is convenient if you only need it occasionally. Assembly was straightforward, and it was the perfect size. It’s a practical piece for apartments, studios, or home offices where you want a quick, temporary partition.
