KLEIN BOTTLE

MULTIBAND MIXER/LOOPER

The Klein Bottle was designed for the noise makers, soundscape artists, endless tinkerers and tone wizards. This epic pedal starts by splitting the input signal into three FX loops, each with dedicated controls for pre-gain, HPF/LPF (bandwidth filters), and mix level. The magic happens when you use the six feedback controls to send the signal from one FX loop into another...and then back again! Keep your existing tone intact with the DRY knob, while layering a cornucopia of sonic goodness on top.

HOW THE KLEIN BOTTLE CAME TO BE

THE STORY

The Klein Bottle was an evolution of an idea that first came to me and my brother Joe independently in 2011. We imagined a pedal that could split the guitar signal into bass, mid, and treble frequencies, and then run into separate distortion circuits. The first iteration of this idea came with the Triumvirate, and then later the full concept was put into the RUP multiband distortion.

 

The big lesson I learned from the RUP was the power of using the FX loops to insert other pedals to create unique FX combinations. At the same time, I was designing a delay pedal under the name "Klein Bottle" that would allow the user to feed three delays into each other - creating an analog way to have the user create a reverb-esque soundscape. After designing a working prototype, I quickly realized that the cost to manufacture would be too great to bring to market - and that the real power still lied in the FX loops.

 

It took a couple more years to finalize the design, but the removal of any internal effects allowed the pedal to do so much more (and cost less to build). It combines both the bandwidth filters of the RUP and the feedback controls of the delay-based first prototype.
