I want to say the Ray24 had a slab body (no tummy cut and no forearm contour). The 24 CA had a slim neck (I think). I like a thick neck, but have played USA Sterlings with the slimmer neck and been good! So, yeah. If you can get around the slab body. The 24 has a 2 band eq, whereas the 34 has a 3 band. A lot of people like the 2 band better! The 24 has the USA MM style bridge And an alnico pickup to sound more like a classic ray. Sometimes you find these at great discount. Try to play one to see if you like the slab body. I have played slab bodies basses and am not all that bothered by them, but it depends on how and where you wear your bass, your technique, etc. I haven't played a Ray 24CA.
