What to check when buying a fretless

[nekomatic]

A brief experience at the NW Bass Bash has persuaded me that it would be fun to pick up a fretless to muck about on, so I’m thinking of picking up a cheapish one and there’s a possible candidate in my local music shop. 
 

Apart from the things you’d check before buying a secondhand fretted bass, is there anything specific I should look out for? I’m pretty sure this one has been defretted, so are there particular signs of a good or bad defret job?

A good, level fingerboard is important, you can't compensate for a small high spot by scraping down a fret.

 

If it has side dots, be sure they are where you want them. On some (mostly defretted) basses they are between fret positions. I learned on a bass with dots at the fret positions and trying to play with the other style is tough as they 'draw' my fingers away from proper intonation.

Normal inspection as per any stringed instrument.
 

The state of the fingerboard (surface condition, radius etc), neck (truss rod) and nut would be my number 1 comment. This is especially important if the neck has been de-fretted. Look for any ridges on the fret-lines and/or excessive gouging along under where the strings lie. The nut height is important if you want the lower action typical of a fretless bass.

 

When trying the bass, first play it without amplification. This will help you discern if the notes sustain well, which helps a fretless bass sparkle.
 

Personally, rolled edges to the fingerboard are a “nice to have”.

 

Remember that a lot of the fretless sound comes from player skill and articulation. Good luck in your search.

The fret dots in the "wrong" place would not work for me, as @Stub Mandrel said, and would probably stop me from buying any kind of de-fret.
