"My perfect sound was an Avalon 737 studio pre through my WJ powered cabs. So I set out to design a bass pre-amp that truly reproduced your bass sound & thus enabled you to tailor your sound. Also the tone controls had to work in the right areas & the pre had to have all the bells & whistles we need to do our job. Again no expense spared, just the highest quality components I could get for everything we need on stage & in the studio. These were my Instructions to my Engineer. I have achieved that with the WJBP. This pre will also make front of house engineers happy as what goes in comes out." ~ Wayne Jones
The WJBP is designed with a no compromise attitude in Cost, Quality, Components & Features just as are WJ High End High Powered Bass Cabinets.
Input 1/4” phono stereo/mono jack
Input Gain For both Passive & Active basses
-10 Db pad with single overload light (located above Pad Button) that lights up Orange when overloading starts and red when clipping. Do not confuse with pre-amp output clip lights.
Tone controls are critically set by Wayne & are extremely accurate in the attack points of each string. You can set them by one for each string on your bass All +15Db -20 Db
Incredible separation between the tone controls
There is also a 30 Hz boost for those that may like it ( not really needed at all as the Bass control gives such a great bottom end with ultimate attack)
In/out button for selection
Compressor: Optical, automatically senses & is very effective even with a very small amount engaged.
In/out button for selection

Clip LEDS (top left corner) tell you if you are overdoing the WJBP output
