RG370DX mod worth it?

Honestly, doing that won't automatically make it a high end guitar but will up the resale value if it's in good condition. The build quality and wood selection (not just the type, the particular slab they used for it and how knotted/resonant/etc it is) come into effect.

If you're going to play it and not sell it within a few years, sure it suppose it's worth it, but consider that you're putting nearly the same amount into the mods as the guitar itself is worth, and you might not get much of that $ back if you ever sell it.
 
No.

The 370DX is made out of cheap wood, and while new pickups might make it sound a little better, you've just put more money in that guitar to upgrade it, than it's worth. Do you REALLY need the Floyd Rose? I say, just stick a piece of wood in there to block the trem and use it as a hardtail.

For a little more than $400, you could pick up a used RG1570 Prestige that would put that guitar to shame.
 
i have two korean RGs, nice guitars if you don't use the trem, but i'm not sure if its worth it to do the upgrades,

if it has some sort of emotional value to you (sounds sentimental i know, but its a valid argument), and you really need the trem, a floyd would probably do the trick no doubt (if installed properly)

however for the sound improvement with the pickups, i am not sure about it
i have sometimes made the mistake on blaming a guitar sounding shit entirely on its shit pickups, which is not always the case
sometimes guitars just don't resonate well and putting good pickups in only turns them from crappy to mediocre

my advice would be get the dimarzios before the trem and see if you're satisfied with the tone,
if it doesn't completely satisfy you, don't bother with the floyd, just buy another guitar where you put the dimarzios in (and put the stock pickups back into the rg370)
 
I had this average RG 270, first non-shitty guitare I owned, and when I changed POWERSOUND stock pickups (great name, huh ?) for used dimarzio (Dual Sound aka Super Distortion with split/phase 4 wires and Air Norton on neck), it REALLY changed my tone for good, but be sure, your tone is :

-20 % guitar (so pickups could be 10 % of the whole chain)
-30 % amp
-50 % YOUR HANDS ! (a good musician sounds good, on crappy tools too)

Changing pickups did a good improvement on the 20 % of the guitar, but a new pickups, most of the time, will change your EQ response, and maybe improving feedback annoyance with distortion.

SO, what I would do is buying used pickups as I did back in the days, and for the floyd rose...too expensive for the guitar

-edit- and yes, you're right, wizard II neck is just perfect for modern players, what a great (and cheap) neck Ibanez use on a lot of their stuffs...I remember improving my techniques so well with this neck, it was so hard to play on another brand after that (it was my one and only guitar for years)

(percentages used in this post are my own interpretation, of course, it is not proven facts !)
 
I wouldn't put X2N's, they are toooooo hot for anything else than playing DM ( Chuck Schuldiner used those) I had one on various guitars ( I just swapped it to see if it was better) and no, it still sounded the same on all.

About the nut...seems like the string retainer thing ( that bar after the nut holding the strings lower) is not set up correctly, the nut is on an angle and you have to force the strings to follow it with the retainer.

That said, I don't think a cheap guitar means crappy tone all the time. I'm currently playing with a cheap RGR08LTD and I prefer it over my prs CE24 for the music I play. If the guitar can hold tuning and is comfortable, the rest can be improved.
