My acoustic basses.

Eko BA4
started it's life as a right handed unlined fretless, decided to put frets in
the headstock broke off twice, thanks to my cats on both occasions, fixed it twice, made a adjustable bridge

Harley Benton B30 NT Acoustic Bass Series 'Deko'
as the 'Deko' tag indicates - for show only ;)  I made it a player, removed a hump between fret 10 and 17, the bridge saddle was also cut too low

Warwick Rockbass Alien Standard 5
