Precision/Jazz Bass and The Thunderbum bass guitar.

3D Printed Electric Bass Guitar – Precision + Jazz Pickup Model + Bonus “Thunderbum” Humbucker Model

This isn’t just a remix of my original 3D Printed Precision Bass

It’s a full-on upgrade. More tone. More bite. More puzzle-piece attitude.

🎸 What’s New

Precision + Jazz Power – The classic P-bass thump meets the growl of a Jazz bridge pickup.

Got Power? - Cavity for 9V battery when using active pickups

Pickguard? Gone. – Electronics mount straight to the body, so the puzzle theme screams in full view.

Bonus Body: Thunderbum – Want earth-shaking lows? The included “Thunderbum” model swaps in two Musicman-style humbuckers for pure wall-rattling punch.
