What output levels does the 45J provide, and how do I switch between them?

The pickup delivers 2.00V in standard finger/thumb mode and can jump to 4.50V in thump output, giving you expressive dynamic range for different playing techniques. Your bass electronics or preamp will determine how you access these modes—check your instrument's wiring configuration.

How long will a 9V battery last in this pickup?

At 80 microamps current draw, a standard 9V battery will last approximately 3000 hours of continuous operation before needing replacement.

Will this pickup fit my six-string bass?

The 45J's 4.5-inch (115mm) soapbar housing and 92mm maximum string width are designed for modern six-string bass bodies. Verify your instrument's bridge-position dimensions against these specs before purchasing.

Is soldering required for installation?

No—the EMG Quik-Connect solderless wiring system allows you to install or swap the pickup without soldering, making future modifications straightforward.

What tone profile should I expect from this pickup?

The 45J emphasizes punchy midrange, articulate response, and tight low end with defined character. Its 4.40 kHz resonant frequency minimizes mud while maximizing clarity, making it well-suited to funk, progressive, and studio tracking work.

Do I pay sales tax on this order?

Sales tax is collected only on orders shipped to California; orders shipped to any other US state are not charged sales tax at checkout when you buy direct from our website. Marketplaces collect sales tax as the facilitator in most states, so the same listed price can cost more there. Buyers remain responsible for any use tax their state applies.

EMG 45J 6-String Active Soapbar Bass Pickup in Black

The EMG 45J is a professional-grade active soapbar pickup engineered for six-string bass players who demand punchy, articulate midrange response and extended clarity across the frequency spectrum. Its compact 4.5-inch housing and optimized 92mm maximum string width fit modern bass designs without compromise, delivering the tight, defined character that defines EMG's active pickup philosophy—essential for cutting through on stage and holding clarity in the mix.

Tone & Electronics

Built around a radiused ceramic bar magnet and humbucker technology with blade pole pieces, this active design yields a 4.40 kHz resonant frequency that emphasizes punch and articulation while minimizing mud. The 2.00V finger/thumb output and 4.50V thump output give you expressive dynamic range for live performance nuance, while 10 Kohm output impedance ensures clean signal transmission to your amplifier without coloration, keeping your tone intact through long cable runs and venue equipment.

Design & Build

The pickup ships with EMG Quik-Connect solderless wiring, streamlining installation and future modifications when you need fast turnaround on the road. Positioned as a bridge pickup, it features a black cover and is made in the United States, backed by EMG's reputation for durability and consistent performance night after night. The active circuit draws only 80 microamps at 9V, delivering approximately 3000 hours of battery life per standard 9V battery—enough to power multiple gigs and sessions on a single cell.
