I had a BX-5 that I bought new in '87 and took to John Carruthers to have it turned into a fretless! He removed the frets, put in plastic filler and added a clear mylar tape to the surface. He also made a curved, dark smoky grey plexi leg rest so I could comfortably play the bass seated.i've had a couple of my extra/spare basses turned into fretless over the decades ... did that to a older Yamaha BX1 headless bass and also a Alembic Elan II ( whoops .! ) ...
In the mid '90s I bought a used Alembic Exploiter and had Kurt Wright make that fretless.
Both basses are long gone, but not because they were fretless. I moved on to ZON fretless basses, and now a Martin Keith Elfin 5 fretless (and a fretted one, too).
My first fretless bass was a '73 Telecaster Bass that I pulled the frets out of after hearing Percy Jones when Unorthodox Behaviour came out.
