I'm parting with my Emma Discumbobulator. Super clean, no issues. I have the factory box, along with the info sheet and the optional rubber feet. I bought this new from Gguitars in New Haven, CT, about 2 years ago. I have owned a SLEW of filter pedals and IMO this is the one of the all time classic filters. It is a little wider than the EH or MuTron, but it reminds me of a good synth VCF, like a Korg filter. It is very quick to respond, and the width control can make the results very subtle, or very deep. It has been just as useful with my active Zon Sonus as it has been with my passive Read J bass. It just requires adjusting the sensitivity control, which is true of any other filter I have used.
