Richard,
I'm kind of finding myself in that situation right now once again. I'm thinking of selling my 2007 VG Stratocaster, which is the newest USA made Strat I have. There's nothing wrong with it at all in fact, it's a very good quality built guitar with a lot of extra features that you don't get in a stock Stratocaster. I just had it professionally overhauled and set up at Lay's Guitar Shop last month, and the action is perfect. It plays like a dream, and holds it's tuning very well.
The reason I'm thinking of selling it is because I also have a 2016 CG-1 Roland ready Strat. That is a MIM Strat that is already set up with the GK-3 pickup and electronics. I can buy a Boss GP-10 and plug it into that guitar and it will give me all that I get out of the VG Strat, and a lot more. That would also be an excellent fly-rig too for places that won't let me bring an amplifier. Having that rig kind of makes the VG Strat a bit redundant, which is why I'm thinking of selling it.
Here's the dilemma: while the CG-1 offers me all the versatility I could possibly want in a guitar, the build quality isn't as good as the USA guitar. I've had to replace the tuning machines, the bridge, the nut and the pickups. The neck on the CG-1 is more like the vintage neck profiles which I prefer over the modern "C" shape. However, I've been checking out the newer Fender USA guitars, and it seems like the quality has been slipping again at Fender. So...what do I do here? Keep it and just use it as a stock Strat, or sell it since I already have two others like that with vintage neck profiles?
I've come to the conclusion that if I have any doubts about selling something that really can deliver flawlessly when I need it, then don't sell it because there's a good possibility I'll regret it. It's the same way with amps and effects.
