AmBASSador of the F Clef
Well, last afternoon i bought a new AGB. I feel the need of a fretless ABG, and i want to play it in an acoustic Klezmer trio (my new 2nd band).
Found a cheap Harley Benton HB30 nearby in some classifieds and bought it blindly (well, for 75€ it just needs to be technically ok). This one:

A few years old, in really good shape, battery empty. It has a scale of 815mm. But i am used to the 800mm (plus compensation) of my fretless V. So the scale must be shortened. The fingerboard and even more the bridge were a bit "raw" - a tribute to the small price of the new instrument (150€). Ok, no problem, as the bass is to be modded anyway.
Here it goes:
remove the saddle (well, bone! in such a cheap bass!!) and cut the fingerboard shorter:

saddle to high - cut it shorter - bone requires a saw. And glue it in. Reinsert the broken piece of the binding.

The bridge was raw with pretty sharp edges. Smooth the surface a bit and round all edges with a scraper and then sand it. The fingerboard needed to be smoothed with the scraper as well. Round the sharp edges of the binding with sanding paper and apply a bit of olive oil to the fingerboard and the bridge.

As i did not have my nice wood at hand i just used some rests of Paulownia from the velomobile project to fill the gap behind the saddle, and then grabbed appropriate strings. Here Pyramid Black Nylon Tapewounds. These strings hav ea warm woody sound and a fast decay fitting well to the expectation of a double bass played pizzicato.
The scale length has been altered by only 12 mm - but thats makes a huge difference for the playability.
