Acoustic Bass De-Fret

Recommended Posts

Been asked to do some acoustic covers with a mate and his girlfriend, and while Acoustic basses are low on my priority list, I wanted to look the part. Having done acoustic gigs using my fretless before, I knew i'd want a fretless acoustic bass. And as i've been playing covers requiring a Five string; it'd need a Low B too.

The problem is they're few and far between under £500 so I set about looking for cheap answers.

Harley Benton do a five String fretless ABG for £150, and that took my fancy...then spotted Gear4Music doing a five string!

Could I defret it? Why not Eh?

Read online (StewMac) that introducing backward bow to the neck opens up the fretlines - I wasnt 100% sold on this idea, but did it anyhow...Also, I oiled the fingerboard as dried wood splinters.

Again, how effective this was i'm not 100% certain. But It was a nice way to spend the afternoon.

So...

I'd read about people heating up the frets. But as this was a budget bass, They didn't seem to need much encouragement.

I Basically pried each fret proud, then scored around each side before gently lifting out the fret.

There was some very small splintering but I'd sort that later. Funny, the first fret was a swine - the rest were easy; i'll put that down to me being too careful/gentle on the first fret.

Took 30 minutes to get this far.

Woodglue, veneers, filled slots - pretty straight forward.

Trimmed them back so the didnt get caught or knocked (2 four year olds really wanting to 'help').

Trimmed tham back with sharp scisors once the glue had set

- one of the veneers split - could've kicked myself, but instead I just fixed it...

I chose rosewood so the lines are semi visible, but at a distance would look fairly plain.

Once sanded, I got around to sorting the surpisingly small and few splintered areas.

Saving the rosewood dust, and mixing it with the glue makes a brown putty - It goes on a slightly lighter shade of brown as the glue starts out white but dries clear - meaning it's more or less invisible.

And...after another rough sand, then a fine hand sand...

Restrung it with the stock strings;

Need to lower the nut slots and bridge to a nice low action - but my needlefiles are at work and the 'pulling the strings back and forth over the nut is a bit of a pain.

Ive also got some Flatwounds at work which are being dropped off later, so at the minute, I havent got the full idea.

Sounds ace though, much better as a fretless.

Nice job. I saw a youtube video series on defretting a bass, which made the process look much more complicated than your series of photos does. In particular, making sure that the veneer is the right width to fit the slots. In the video I saw, he had to sand the veneer thinner. How did you make sure that the veneer fitted?
