Mike Lull has collaborated with Pearl Jam’s Jeff Ament to create the JAXT4 signature bass. It marks the first time any member of the group has put their name on an instrument.

The bass has an oversized body, cut thinner than a standard Lull T4, and with a reverse headstock. Select models have a pickguard engraved with an Ament-designed T-bass logo, Ament’s signature on the headstock, and a special Lull logo. It ships in a custom hardshell case with hand-stenciled logo and a bag of Ament custom guitar picks. The JAXT4 is available in these four custom color and wood configurations chosen by Ament, including;

• Satin black polyester with chromed aluminum pickguard on a mahogany body with mahogany neck and rosewood fingerboard.

• Satin kerry-green polyester finish with white plastic JA pickguard on a mahogany body with maple neck and maple fingerboard.

• Gloss clear polyester finish with chromed aluminum JA pickguard on a swamp ash body with maple neck and maple fingerboard.

• Satin cardinal-red polyester finish with solid black plastic JA pickguard on a mahogany body with mahogany neck and rosewood fingerboard.
