I wanted an ES-135 for a long time and finally got a really sweet deal on one. A couple years later I discovered the G6120N, so now the 135 isn't getting played any more. I suppose it would come back out.Now, this is an interesting question! I've come back, time and again through my life, to the Gibson SG - they fit like a glove. For something formatted more like most Gretsches, I think I would stick with my ES-135 and ES-137.
But then again, there's always a Hofner Club.
But more for the Flying V than the SG. Once I bought an Epi V back in the 90s as a backup guitar. Then I started playing it and it became my main guitar. The Epi V has been through the shop for wiring and Seymore Duncans. So I still have it. But I also picked up a Gibson V and put Classic 57s in it. I still pull out the V if I have to play up the neck, or for some occasions. For me the V fits like a glove. The lower bout goes up against the right thigh and I everything is in just the right place.
But I do have an SG that I put a Bigsby on. Just in case I need to play some Alice Cooper.
