West Co Pedals releases the Curt “Kirkee B” Bisquera “Grease Juicer” fuzz / envelope filter pedal


West Co Pedals has announced the release of their first signature pedal, the Curt “Kirkee B” Bisquera “Grease Juicer” – an envelope filter pedal with attitude. The Grease Juicer features a unique analog signal path with knobs making it easy to control its complex chain of fuzz into an envelope filter with a sidechain. Two versions are available-one pedal is voiced specifically for bass and another tuned specifically for electric guitar. If players want a little extra grease and grit this pedal delivers, but it can also function solely as an envelope filter for a clean sound. The envelope filter was designed to accommodate a massive dynamic range-everything from very quiet playing on a guitar with low output single coil pickups, all the way to thumpin' n' pluckin' on a bass with active pickups. The Grease Juicer also sounds incredible on synths, electric piano, and clavinet. To get the kind of sounds and control that the Grease Juicer offers, it would normally take 2 or 3 separate pedals. The Grease Juicer is available through Clif Jones' LA Vintage Gear store in Burbank, CA, or through the West Co website directly at for $329.99 USD.

One of the most “in demand” drummers, Curt Bisquera came to West Co Pedals to collaborate on an envelope filter for bass players to use while recording and performing. Bob Daspit, the founder of West Co Pedals, was able to realize Curt's vision-and then took it to new heights by adding the guitar pedal version. “I have been designing and building pedals on my own for several years, and now it's been incredible to work with a great musician like Curt to bring the new sounds of the Grease Juicer to life. We've been getting great responses from our artists,” says Daspit.

John-Paul McLean, the bass player for Melvin Seals and JGB (Jerry Garcia Band), tried the Grease Juicer recently and immediately exclaimed, “This is exactly what I've been looking for!” (

“I've been using the Grease Juicer on this latest tour with John Legend,” said bassist Kaveh Rastegar. “I've also used it in the studio. It sounds great and is super dependable. I love this thing!!”

Bisquera noted, “For 30-plus years I've been playing with the most world-renowned artists and musicians – it just made sense for my first collab to create something for bassists, guitarists, and synth players that I knew I wanted to hear when I'm playing drums!”

As a composer, Daspit has created original music for films, animation, and video games including Stuntman: Ignition, Terminator 3: Rise Of The Machines, Mission Impossible: 2, Terminator: Dawn Of Fate, and the cult classic Spy Hunter. As a guitar player, Daspit found himself in demand as a top session player for such composers as Harry Gregson-Williams, John Powell, and Michel Colombier. Hans Zimmer favored his blistering guitar work on a number of popular films such as Drop Zone, Point of No Return, Broken Arrow, The Rock, and The Fan.

Working with famed virtual instrument maker Spectrasonics, Daspit created the landmark sound libraries, Hans Zimmer Guitars Volumes I and II.  Released by Spectrasonics, the two collections explored the wide range of guitar tones and other unique stringed instruments.

Hagar's version of Let Me Take You There was Daspit's first charting single that he recorded, mixed, and produced in 2005. Daspit hit the charts again in 2006 producing Hagar's Livin' It Up featuring the single Sam I Am (which Daspit and his wife Nicole also co-wrote). Shortly after producing Hagar's solo record, Cosmic Universal Fashion, Daspit received his first gold record for his work on the debut release by Sammy's all-star band Chickenfoot.

Bob founded West Co Pedals in 2015 after learning electronics from his father John Daspit – an inventor and electrical engineer who has been designing products since the late 1950s.
