Trickfish J-Core pre-amp, 4 band with knobs £200 Bristol

[Johnebass]

As new, only used once and in the original box as you can see from the pictures. Don’t know why but I preferred my Sadowsky pre-amp.

 

As you would expect, this unit is in immaculate condition as it was only in the bass for a few weeks. All in the original box.

Technical info:

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.

Powered by the incredibly flexible and supremely musical Mike Pope-designed preamp with a 4-band EQ, the J-Core puts tonal control at your fingertips. With internally selectable EQ points for each band and refined signal path enhancements, it’s designed to bring out the best in every note you play.

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

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 centres 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.

With selectable frequencies at 46Hz or 90Hz, 330Hz or 473Hz, 600Hz or 900kHz, and 6kHz or 10kHz, the J-Core offers precise control to shape your sound exactly how you like it. Additional switches allow for 0, 3, 6, or 8 dB of output gain.

A hallmark of a truly versatile Jazz Bass is its passive tone control. Some players prefer a subtle tone roll-off that preserve’s 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.
