Mike Lull JAXT4

As of October 2019, the JAXT4 has been discontinued in response to a legal threat from Gibson.

Longtime Northwest guitar and bass builder, Mike Lull, has collaborated with Pearl Jam's Jeff Ament to create the "JAXT4" signature Jeff Ament electric bass. This handmade instrument marks the first time any member of the iconic, 20-plus-year-old musical group has put their name on an instrument.

Capitalizing on a 25-year relationship, Lull and Ament worked together closely to create the signature model bass. The bass features a 20% oversized body, but thinner body thickness than standard Mike Lull T4 models, along with a reverse headstock. Jeff Ament personally chose all custom colors, finish, and wood configurations.

The JAXT4 comes with a chromed aluminum JA pickguard engraved with an Ament designed T-bass logo, Jeff's signature on the headstock along with a special Mike Lull logo designed by Jeff to be used only on his signature model.

Included is a custom Ament hardshell case with a hand-stenciled logo on the exterior, along with a bag of assorted Ament custom guitar picks.
