Ian Martin Allison IMA4

Mike Lull IMA4

Is it a Thunderbird? Is it a Jazz? Is it an ergonomically and tonally-improved amalgamation of the two? Maybe…. We think so…. It’s an IMA4.

We worked closely with Ian to create the perfect blend between a Jazz and a Thunderbird. What transpired was a masterpiece. The IMA4 was born.

This what Ian had to say about the new IMA4, “I am thrilled to announce a collaboration between me and Mike Lull Custom Guitars. This is the IMA4 and it’s incredible - all the things I love about a 70s jazz combined with the the best features of a Thunderbird with some fun twists. Although I helped design it, there is no signature graphic, decal or branding on it of any kind; I am so excited for it to be YOUR bass. There’s nothing like it on the market. It absolutely rules.”

The IMA4s are produced in highly limited runs. When they’re gone, they’re gone!
