Keeley Electronics Java Boost

Item: FE0868515002

The Java Boost is a germanium based treble booster. It is not a clean boost. It is designed to give you classic tones from the 60's and 70's, and man does it ever! It must be used with a cranked amp that is overdriven or distorting a bit already. The more the amp and pedal are cranked, the more the creamy, beautiful, sustaining distortion there will be.

What makes this pedal kill of the hill is that it has the real deal, no joke Mullard OC44. Yup, Made in Holland. Keeley has only a small number of the OC44 and CV7003 transistors. Please order soon, as this will be a limited edition pedal. Looking for the Ultimate in Boosters? The Perfect Boost for your main overdrive pedal? From Surf to Fuzz, it's the best cutting and biting tone from a pedal!

Keeley Electronics Java Boost Features:

  • 3 way switched treble-booster, Stock Vintage Rangemaster (center), Mid-boost (to the Right), and Full Range(to the Left)
  • The switch is a very expensive locking 3 way switch so your setting is not moved.
  • Metal film parts for low noise.
  • Best part, the ultra rare Mullard OC44!
  • This is the transistor used in the mid 60's and only the best survive our critical testing. Low leakage of 150uA or less and Hfe of 80-110 are minimum requirements for the transistor to be used in our circuit.
  •  The CV7003 might have a little bit more overdrive and be a bit quieter. These are very hard to measure or give you anything more than these general statements. They are in fact the exact same transistor. Units that tested better were marked as CV7003, the mil spec number. Since each transistor has it's own sound, each unit will have a slightly different tone.
  • Keeley Blue LED.
  • Each unit is perfectly dialed in internal potentiometers let us fine tune each of the tested and passed OC44's for optimum operation.
  • Tone Control!!! Yes ours has a second way to control the frequencies of the boost made, plus the Standard Level Control.
  • True-Bypass, Switchcraft jacks.
  • Powder Coated case just like the Keeley Compressor
  • Stamped serial number.
  • THE Benchmark for all other Dallas Rangemaster pedals.
