J-Boost

J-Boost Clean EQ/Volume Boost

Incredible Tone Enhancement—

The Ultimate Compressor Companion

A terrific combination of power and refinement, the clean, non-compression JangleBox J-Boost is the perfect companion to any JangleBox compressor, and a stand-alone enhancement to virtually any pedal in your rig.


Special features include:

Unparalleled tone refinement. Unlike some other boosters, the J-Boost is a total EQ boost, not just a glorified volume knob.


  • Full tone flexibility. By adjusting a single tone knob you can use the J-Boost as a treble boost, bass boost or even a mid boost. Or you can tweak your overall tone to perfection by eliminating low-end dullness or ice-picky highs.


  • Ultra clean output. Yes, the J-Boost can help drive your amp to the breaking point if you want, but the distortion-free circuit is designed to deliver pristine tone and clarity.


  • Because the Attack and Gain knobs on most compressor pedals are interactive (as on most JangleBox compressors), it can be very difficult to create louder output volume with low-level compression. The J-Boost fixes that by allowing you to lower your compressor's Attack to just a hint of compression and still get a clear, booming output.


  • Use it with any JangleBox compressor to create an unbelievable richness and depth of tone. And by combining the J-Boost with our JB3 or JBX, you can even create a boost-on-boost-on-boost!
