Yes, in all but one important difference, the neck on the RG1702 is an Ultra (like the 2020/2120X, RGT, or RG-PR series). Another less significant attribute is that the 1702 has the
strap locks inset into the body, it is a very cool and unique feature but unlike the 3120, which can use strap locks or a regular strap, the older inset strap locks will only allow a strap to be connected if it is using the locks that go with the same type of locks installed in the body. (hope that makes sense)
