This is a Squire Bronco 30 inch scale bass that has been converted to a fretless finger board.  I became interested in playing fretless bass and tried a 34 inch scale fretless.  After a few months of practice and a gig or two in decided to look for a short scale fretless because the 34 inch scale was too big for my reach.  I could not find an affordable short scale fretless so I decided to get an affordable fretted short scale and do the fretless conversion myself.  I have done enough guitar work that this task did not scare me.  The line of Squiers by Fender are good quality instruments so I chose the Squier Bronco.  Here is what I did:

*  Pulled the frets and filled the slots first with wood glue and then a light urethane coat and then fine wet sanding.  The finger board feels nice and smooth.  Not a perfect pro job but completely playable with no problems fingering the notes.
*  I used a soldering iron to lightly burn side markers at the fret locations.  This was very helpful to get correct tuning while fingering
*  The factory pickup had a very thin sound.  I was disappointed in this so I replaced the pickup with P bass style pickup from a Fender American series bass.  This improved the sound very much.  I routed the body and cut the finger guard to accommodate the new pickup.  The mounting screws for the pickup probably need replaced for more fine adjustment of the pickup height - I practiced and played out with it as is.
*  I replaced the bridge with a higher mass bridge that I had in my parts bin.  Probably helps the sound.
*  I stained the edge of the all white pickguard to give the guitar a little more impact visually.
*  I put a decal on the head from one of my favorite breweries (Bad Martha's).

The upgrades I made can be seen in the pictures.  I also posted a picture of a factory fresh Bronco for comparison.  

I spent a couple grand on a beauty of a short scale fretless so I guess this experiment was a success!
