Keeley Effect Pedals - USED Java Boost Pedal - CV7003 Transistor

SOLD - Contact us for more options
Free Shipping Eligible

This used Keeley Java Boost, here in Very Good condition, is essentially a treble booster, specifically designed for use with an already cranked-up, overdriven amp. This particular pedal is one of the first, serial number JB174, and it features the highly-sought-after CV7003 transistor, as well as Robert Keeley's signature inside the pedal.

It's long been one of our favorite pedals for those who like to kick it up to eleven. Perfect with tube amps and amazing when run before a Blues Driver or Tube Screamer pedal - it really maximizes the results. Once you hit that sweet spot you won't let go - super sustain and killer tone. The Keeley Java Boost is a beautifully designed pedal made tailor made for rock and roll.
