Keeley Java Boost:
The Ultimate Rangemaster clone. What makes this one raise ears and eyebrows is that it has the REAL DEAL, no joke Mullard OC44. Yup, Made in Holland. Keeley Electronics has only got 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...the best cutting and biting tone from a pedal!
The Java Boost is NOT AT ALL related to the TS9 or Blues Driver, OR ANY distortion or overdrive pedal. Boss or Ibanez don't make anything like it! It is a Treble Booster by design, not a typical overdrive or distortion pedal. That means, the higher the note played, the more it gets amplified... and then, by your amp, distorted. Bass Notes get Cut in two of the modes on the Java Boost!
For best results, it is mostly used with a tube amp that is already set for a bit of overdrive or clipping. For example, setting the Java Boost in front of a very clean amp with the volume on 1-2 will surely result in a fairly weak guitar tone.
Set the amp for some breakup, say at 4-5, ao that the amp is already making some Texas Dirt Tones (break-up/overdrive), then click the JB on, and you will have a fantastic sound and see why people rave about the Java Boost.
A Closer Look:
- Modern Dallas Rangemaster Circuit
- 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 Keeley's critical testing. Low leakage of 150uA or less and Hfe of 80-110 are minimum requirements for the transistor to be used in this circuit. Some pedals ship with the CV7003 (the Mil-spec version of the OC44), which 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.
- Second best part, DC jack and Negative ground system so it will work with your other supplies and effects and no smoking! BATTERY power is really the best way to power this device. Because of its simple nature, ANY POWER SUPPLY WILL CAUSE NOISE. Keeley Electronics has designed in measures to reduce this noise, but it will still appear even with the best supplies. Batteries will last 48 hours of continous use in this unit.
- Keeley Blue LED
- Each unit is perfectly dialed in ...internal potentiometers let Keeley Electronics fine tune each of the tested and passed OC44's for optimum operation
- Tone Control
- True-Bypass, Switchcraft jacks
- Powder Coated case just like the Keeley Compressor
- Stamped serial number

HARMONY CENTRAL USER REVIEW:
"I especially like Robert's trademark Blue Light. It's easier to see under stage lights and at outdoor gigs. I don't think I would add anything else to this pedal nor would I wish for it. It's pretty perfect as is."
HARMONY CENTRAL USER REVIEW:
"I play a few styles of electrified music. Almost 20 years playing. I am really diggin this thing. Probably a bit expensive for the average young guitarists. But I would urge them to save there $ , hold off on that mass produced ped , and get something like this. Because I'm poor I'll give it a nine. Take my financial situation out of the pic and.... this thing is ten!"
HARMONY CENTRAL USER REVIEW:
"If stolen I would definately get another. This is the piece of gear with the sound I have been looking for. I have bought all 3 Keeley pedals without playing through them first. No regrets. I am posting these reviews because I think Robert deserves them. A true credit to the business and music industry. I am waiting for his own made from scratch overdrive,chorus and phaser."
HARMONY CENTRAL USER REVIEW:
"I play rock, blues, and jazz. This pedal fits them all! Great lead tones, and a nice, warm mild overdrive for jazz. I've been playing for about seven years, and great products like Keeley are what help keep me inspired. This, coupled with an overdrive,is all I need to nail any tone live! If you like the dirt of fuzz, but think it's to dirty and unresponsive to your playing, buy this. If you like the warmth of OD, but want more gain options, buy this!"
