Finally, the headstock logo on the Dot is.
Another significant difference is that the pickguard on the Dot is mounted on top of the binding, while on the Casino it is flush with the body. The Dot also has a slightly thinner body than the Casino. I have however played a Tokai Japan ES178 (335 Pro Copy) which belongs to the young guy who runs the local Buskers' Night and I have to say, it's probably the best guitar I've ever played! So much so, that when I got home I immediately looked them up on eBay.…. The Dot has a shorter 24.75 scale length, while the Casino has a standard 25.5 scale length. I also think the 335 Pro with the block inlays looks much nicer than the 335 Dot.
I've not played an Epiphone 335, but I have played a 339 which was a decent guitar. If I had my time again, I'd *probably* go for a full size Casino, although I've never owned a 335 sized guitar. I haven't gigged it, but it nails the late 60's Beatles sound through my AC15. Tonally, it's quite different to any of my current/ previous guitars due to being hollow bodied, and P90 pickups. My observations are that build quality and finish are very good, neck is medium, comfortable and playable, action is low, but could probably be lower with a good set up. I think I paid about £200 for it, and when it arrived it was in pretty much pristine condition. I bought a 'used' Casino Coupe in natural last year when I was on a major Beatles/ John Lennon kick.
