DESCRIPTION

The J-Core preamp takes Trickfish's 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.

Powered by the incredibly flexible and supremely musical Mike Pope-designed preamp with a 2-band EQ, the J-Core puts tonal control at your fingertips.

All this, plus a 9-volt battery, fits neatly into your existing Jazz Bass control cavity. Effortless design meets exceptional sound.

A hallmark of a truly versatile Jazz Bass is its passive tone control. Some players prefer a subtle tone roll-off that preserves midrange presence, while others lean toward a darker, more classic passive tone. The J-Core comes stock with a .022 Cap and can be easily customized with an additional through-hole parallel capacitor.

For years, the Flexcore has set the benchmark for players seeking unparalleled fidelity, clarity, and warmth from their active instruments. Until now, however, it wasn’t available as a drop-in replacement for Jazz Basses.

With the J-Core, you can finally bring the renowned flexibility and performance of the Flexcore into the Fender universe — elevating your sound without changing what you love about your instrument.
