Description
The J-Tone is a new on board preamp with a fully passive signal path and a high spec professional active preamp. It is designed to fit directly into any jazz style bass without the need for invasive modification to the instrument. In passive mode, the original jazz style bass is fully maintained since the signal path is a replica of those in the original Jazz. The preamp comes in two versions:
- Volume / Volume type allows control of each pickup individually.
- Volume / Blend version allows the pickups balance to be set with the Blend, and a Master Volume for the overall output.
Summary of Features & Basic Spec
- Classic Volume / Volume / Tone passive path version, replicating original J style wiring.
- Volume / Blend / Tone version for those who prefer a master volume.
- Push-Pull active/passive on Passive Tone.
- Class A FET input stage for great sound quality, with master gain trim preset adjuster.
- Highly responsive Bass and Treble control adjustments in active.
- Frequency Wheels to set the width of the bass and treble spectrums individually.
- Passive Tone is always operational, in both active and passive.
- Passive Tone has plug-in tone cap to allow easy swapping of the cap value for different roll-off frequencies.
- Bass control can be set as boost/cut or boost only, with an internal jumper link setting.
- Screw terminals for all external connections – pickups and grounding, for easy installation.
- Designed as drop-in replacement for standard J electronics with no physical changes to the instrument*.
- Design allows 9V Battery to mount beneath the preamp in a standard J style bass.
Note: * The J-Tone will fit in the majority of J style basses, but the routing width and depth of cavities does vary, so we can’t guarantee it. It’s important to check that a 9V battery drops into the cavity close to the jack, and that there’s a depth of 32mm.
EASY TO FIT, NO ROUTING OR MODS TO MOST J STYLE BASSES.
A STANDARD PP3 BATTERY FITS UNDER THE PLATE IN THE STANDARD CAVITY IN MOST CASES
