The JZ3 preamp series have been upgraded to the Pro JZ3 Preamps.
Our Jazz preamps will make your bass feel and sound like a high end custom bass.
The Audere JZ3 models shown on this page are designed to replace a standard Fender type jazz plate where the output jack is located on the plate. If your bass has a body mounted side jack then select a JZ3D Preamp or a JZ6D Preamp.
Easy installation allows for players to install their own preamp
Our jazz preamps are complete units, including knobs and control
plate, making installation very simple. Over 95% of these units are installed
by the player. If you have access to and can use screwdrivers and
a wire cutter & stripper then you can install your own preamp which
will save you a lot of money.
3 different configurations
Can't decide? Hard to lose in this tradeoff but if you don't know which one is right for you, then I'd recommend the vol, mid/bal and treble/bass.
Z-Mode Switch creates multiple voices
Our JZ3 preamps feature our unique Z-Mode control. It delivers 3 organic bass voices with clarity and definition. The Z-Mode switch reconfigures the preamp to change the loading applied to the pickups. Pickups interact with the vibrating strings differently in the modes and this changes the voice of the instrument.
In summary, the switch gives you 3 organic starting points, from which you can tweak pickup balance and add tone control.
Our Z-Mode switch makes the Audere preamps not only the best sounding preamps but also the most versatile tone range in the preamp market.
Easy to get a good tone
All of the Jazz models sound the same when the tone controls are flat - they sound like your true bass, and as players find out, that is generally a great sound. The sound is natural in all tone control combinations.
Precision pickup mixing
The pickup signals are buffered from each other. After the buffer they are mixed together by a balance control or dual volume controls. This design provides a broader range of usable sounds as you mix the 2 pickups together and works especially nice for a PJ configuration.
In the JZ3 product you get either a 2 or 3 band tone control depending
The JZ3 preamps will run about 250 hours on a premium 9 volt battery. Normally the battery is placed below the preamp in the jazz cavity. You can connect the preamp to a 9 or 18 volt battery box if you have one installed in your bass.
When you first insert your cable the preamp will power up and show you the battery strength by modulating the intensity of the Blue LED for 3 seconds. When your battery is needs to be replaced the LED will start a different faster sequence for 5 seconds. At this point you still have 10+ hours of playing life so it will not die on you at a gig.

Setup to play great out of the box
Preamps are shipped pre-optimized for a US Fender Jazz bass. This optimization works well for most pickups and basses but you can customize it if you want to. There is more information on these adjustments on the links below:
Fits most Jazz basses
The current American Fender Jazz Bass has a cavity that measures approximately: 1.19" wide at the top (some cavity narrow slightly at the jack end), 1.27" deep, and 5.17" long.
Most jazz style basses including current Fenders made in Mexico and Japan have the standard cavity size. A few other bands may be different and some older Fender basses, especially vintage models, may vary from these dimensions. Normally the limiting factor on the cavities size is the width required to fit the battery in.
When you check the size of your cavity, our preamp needs cavity dimensions of: 1.1" wide, 1.2" deep and 4.8" long.
Already Changed Out Your Pickups?
Common customer replacement pickups we see include Nordstrand, Bartolini, Fralin, Basslines, DiMarzio and various forms of the Fender custom shop pickups.
Important Restriction if you have Active Pickups
To use our Z-Mode technology, you must have PASSIVE PICKUPS, meaning that the pickup does NOT have a semiconductor component in it. The vast majority of basses have passive pickups. EMGs are the most common active pickups. If you are uncertain about your pickups, google them (fastest), check with the manufacturer, or send Sales an email.
