20th anniversary models will hold a bit more value if you ever have to resale, they supposedly came with a special certificate, case, engraved trem cover and strap
I know it doesn't have the v7 and 8, but there's 100s of listing on eBay since Alot of people hate them. (I don't mind them) I've purchased 4 or 5 sets over the last few years and never spent more then $50 for v7 s1 V8 bundles.
As far as moding the guitar, I know the feels.
However the 550 is pretty easy and noninvasive to swap things out.
I didn't want to mess with my 87 550, but you only need to unsolder 2 wires from the Input Jack and tremolo claw.
Literally everything else can be pulled up untouched and stored safely in its case.
From there, not including the pickups, it would only be like 25 bucks for pots switch and wire and you can literally go back to stock by soldering 2 wires, and move your new pickup set up to any 550 type guitar without disturbing the set up.
All that said,
Have you considered just going for a Genesis?
They are great 550s and come with the v7 and V8 combo.
I have seen many Genesis in the original neon colors on reverb pretty cheap. Ranging 600 and up.
I actually got my road flare red Rg 550 for 500 new! (And I'm a lefty)
The feel is pretty great and is almost identical to my original rg 550 from 87.
The only difference is the neck and personally I feel that change is warranted. It will add to the longevity of the guitar.
The only big issue I had is that it's a prestige guitar that doesn't come with a case.
That said if you can get it cheaper then retail, you can always buy a case with the savings.
What Color are you after?
Thanks for the detailed info.
I have to look more carefully, but I don't think mine has the certificate. The case is beat up but it came with the special case.
And thanks, that's really helpful to know about the mods being non-invasive. I was worried I'd ruin the resale value by changing pickups and messing with the wiring, but if it's minimal and doesn't affect the guitar or value then that makes me feel better about being able to modify it.
Glad the V7/V8 sets aren't too pricey. Are the V1/V2 pickups from 2007 highly desired usually or worth more?
And wow 500 is a great deal! I did and still am considering the new genesis guitars, they were actually the first ones I looked at. But I tried a road flare red 2018 genesis model in the store too, and it sounded and played worse than both the 2007 RG550mxx and the 2019 RG550dx. I was surprised that the 2018 road flare red genesis was worse than the RG550dx since they're essentially identical guitars except for cosmetics, but it might have been due to a poor set up in the RFR genesis guitar.
I'm looking to get road flare red or dessert sun yellow. Love both of the neon colors. If I found a 2018 RG550 genesis in either of those colors that played and sounded as good as the RG550dx, I'd take that first.
Seems like there's good deals out there though, so maybe I'll pass on the RG550mxx for now and try to get my hands on a neon colored genesis model that plays and sounds good.
