back-to-basics building leveller

Unapologetically rejecting advancements in 4-string design, the Thundermaker looks back to a time when inspiring awe, terror and an ear-to-ear grin from everyone in the first five rows were a bass player's key requirements.  This friendly giant delivers warm, rounded tones through a combination of chambered swamp ash construction and custom wound Mojo Pickups, but kick in the bridge soapbar (or, if you dare, the series-mode toggle switch) and get ready for some seriously aggressive 60's bite. Available in long (33.25") or short (30.75") scale length

key features:

Looks old, plays new

The Thundermaker's retro appearance hides some very modern features, such as graphite neck reinforcement, a compound fingerboard radius and flexible pickup controls.  We offer a choice of scale lengths to suit your individual playing style
