Unrivalled Versatility
The key to maximizing the eectiveness of the JB3 is to understand
the basic setup. The On/O switch (red LED) controls the Bass,
Treble, Gain and Attack functions. The J-Boost (blue LED) controls
the J-Boost Gain and J-Boost Bass and Treble. The Attack knob is
common to both sides of the compressor. When the J-Boost is
activated, the regular Bass, Treble and Gain are inoperable.
Among many variations, the J-Boost can work as a treble or bass
boost, or, by adjusting the J-Boost Gain louder than the regular Gain,
can create a “boost-on-boost” eect.
