Fretless ConversionÂ
You Can Jaco Your Bass.Â
What do we mean by that?
Jaco Pastorius took a Fender Jazz Bass, ripped the frets out with a butter knife, filled the slots with wood putty – and changed music forever. From Portrait of Tracy to Continuum, his tone was unmistakable. Soulful. Singing. Fretless.
Now it’s your turn.Â
For just $27, you’ll get our full Fretless Conversion Course from Build Bass and Upton Bass. We walk you through every single step to transform any bass to get that smooth singing fretless sound.
No fancy tools needed.Â
We’re talking nail clippers, sandpaper, a sharp blade, your old strings, and some DIY attitude.
Did you know that less than 1% of electric basses are fretless? That means you’re about to stand out. You don’t need to spend $1,000+ on a factory fretless.
You need an afternoon and this course!
$27. That’s it!

hosted by Upton Bass.
I’m Gary Upton, founder of Upton Bass. We specialize in crafting high-quality double basses, working with top artists in the field. Over the years, I’ve gained valuable insights into instrument-making that I’d love to share with you. While I started with no lutherie experience, I’ve since trained numerous luthiers here at Upton Bass, and in our courses, we share key methods of instrument building, setup and modifications.
