Evolution is about enhancing and expanding desirable traits while reducing unwanted traits. That was Leo Fender’s† mission for G&L, and that’s exactly what the new MJ-4™ accomplishes The active MJ-4 features G&L’s new Bi-coil Alnico V pickups and MJ-spec preamp/control system for a wide range of single-coil tones from classic jazz to far beyond, all without single-coil hum.

A G&L Alnico Bi-coil pickup looks just like a classic Alnico single-coil, but under the cover are two side-by-side coils, configured in series-humbucking mode. The new pickups are optimized for a specially tuned version of G&L’s studio-quality M-spec preamp and control system, dubbed MJ-spec. The 18v system features volume, pan and +/-14dB 3-band EQ with center detents, and is powered by twin 9v batteries housed in an easy-access compartment. With an LF442 chip, 100v poly caps, 1% metal film resistors and big, fat signal traces on the mil-spec circuit board, this preamp reveals everything the player and the instrument have to offer.

  • • G&L Bi-coil pickups for classic tone without the hum
  • • MJ-spec studio-quality 18v preamp
  • • Primary volume and pan controls to explore the full range of sounds available between the two pickups
  • • +/-14dB 3-band EQ with peripherally placed, center-detent, reduced-diameter knobs
  • • An impeccable, familiar “feel” of the instrument in the hands and on the shoulder
  • • 1 5/8” nut-width, medium C neck neck profile
  • • Medium-Jumbo, Plek-dressed frets

Ed Friedland, "The Bass Whisperer," has posted a thorough demo and review of the G&L MJ-4 bass. Ed walks you through the wide tonal variety provided by the MJ-4 and gives some great tips on dialing it in for different styles of music.

In the end, Ed confesses, "I'm just going to come right out and say it. I love this bass! I've been playing it on gigs now for several months, and it just makes me happy. It does everything I want a jazz bass to do, and it does a whole lot more. And, it does it all really well."

Bass Player Magazine on the MJ-4:

"I loved the feel of the satin #12 neck; it's a great mid-point between the P and J profile"

"The bass sounded like a great active J with exceptional note clarity, punch, and a flexible EQ system"

"The preamp is powerful, and seems well tuned to the pickup response"

"The MJ-4 is an excellent addition to the world of active J basses, and considering its champion bloodlines and U.S.-built pedigree, the bass not only stands out as a bargain compared to imports of the same price (or higher), it gives its siblings a run for their money."

Pros: Punchy active J-Bass tone, great build quality, competitively priced.

Cons: None

Bottom Line: The G&L MJ-4 is a top-notch American-made J-style 4-string at a price that's hard to beat.
