The J-Core preamp takes our widely acclaimed Flexcore Onboard Bass Preamp to the next level—
now in a hassle-free Jazz Bass plate drop-in design. No modifications, no soldering, just pure performance
We’ve swapped out traditional jumper-style selectors inside the J-Core for intuitive rocker-style mini switches.
These make it easier than ever to fine-tune the frequency centers of each of the 4 EQ bands, allowing you to customize the EQ to match your bass’s unique voice and your personal tonal preferences.
All J-Core preamp kits include: Prewired output jack, battery connector clip, preinstalled on a jazz bass control plate.
