Here's some love for the EBS BassIQTriple Envelope Filter - a little warrior that deserves a mention.
Sweden's EBS launched this unit in 2000 (has time really passed that quickly??), the company's 5th pedal creation following its initial success with the Octobass. After experimenting in 1999 with a pedal for guitarists - the Red Twister Chorus - the company went back to its roots with this purebred bass pedal.
The BassIQ has carried the familiar compact but tough-as-nails form factor throughout. Some updates in 2008 to add true-bypass, additional headroom and new analog circuitry have seen the design through to the present day.
In terms of sound, it has a smooth quality; not a crazy, experimental filter: this is a straightforward filter for everyday use. With three modes (Hi-Q, Up, Down), there is still a great variety of sound available, though it seems particularly suited to funk.
And it might just be my favourite filter so far... a close competition though with the Subdecay Prometheus as far as compact, real-world-usable filters go.
