VFE - Klein Bottle

Instruments Category: 

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.
