The SC58s, Stripped 58s, and 245s all have the two piece bridge like the 594s.The difference is that the bridges are machined aluminum instead of zinc, and of course the scale length is 24.5 inches instead of 24.594.
Here’s a pic of my SC58 that I foolishly let go; I also had a Stripped 58 and an SC245.
Currently I have a McCarty Singlecut that was a PS model. It has a slightly thicker body than the other Singlecuts, but doesn’t have the 594 scale length. It has the more vintage tones of the 594 despite the differences. This is my #1. If you can find one, they’re fantastic instruments.
