A couple of days ago I fitted a couple of Schaller strap locks to this bass. My woodworking skills are not good enough to remove the dunlop strap fittings on the bass so I decide to leave them as they are not protruding. This bass is a bit lighter than my SC Deluxe so I was hoping the balance point would be better using the standard fitting points. However, it is actually worse with more severe nose dive than I expected. :-(
The position of the dunlop strap fitting at the bottom of the bass, as you may see on close inspection of the photo's, seems to be a much better balance position for me anyway as the bass stays more or less in position and does not lean forward at the top as much and relies less on my holding it in place with my forearm whilst playing.
So it seems the previous owner who installed the dunlop has found the right point for balancing the bass for playing. On my strap I now use the schaller at the base of the neck and a choice at the other end of either dunlop or schaller, but I'm actually using the dunlop one.
Hope that makes some sense.
