This is a hand wired Kit version (ver. 2.6) of the original VFE Klein Bottle purchased directly from Peter Rutter. All parts are high quality as purchased from Mouser Electronics via Peter’s BOM link.

It is in very good condition. This pedal is a lot of fun to work with! There is velcro on the bottom.

Everything works as it should with the following exceptions which is why I am selling it at a reduced price. I did not think it was worth taking apart to fix these (minor) issues.

1. The Channel 1 status led is intermittent. The light comes on when you gently touch the led. The channel footswitch is fully functional.
2. The Channel 1 6/12 db micro switch which changes the filters’ slope is broken. I covered the hole with a piece of black tape.

The Klein Bottle is a unique three-loop parallel effects mixer/router that allows you to combine and interact with effects in ways that aren't possible with a conventional pedal board signal chain. Each loop has extensive level, filtering and routing controls, making it an unusually powerful tool for experimental effects processing, complex parallel chains, and sound design.
