Yeah, I'd recommend you try them - they do differ a bit.
Reading this reminds me that I tried Philly's at a London meet, and it didn't really "speak to me" when I played it. I assumed at the time that this was because of the colour (black with a maple board, and it hadn't got "polished" up like they do when you own them for a while), the type of geetar (it was a tele thing with humbucker), or some other imponderable I couldn't identify (but it was a "new" guitar for him that week or so, so I wasn't going to start looking for reasons to explain why it didn't grab me personally! :lol:).
It hadn't crossed my mind at all that it might not be as lively an instrument as I was expecting - the two Roadworn strats I own (one of them was with me) and all the 50s RW teles I've tried are lively as hell! :lol:
On the finish, I can confirm what Philly says - both my RWs feel like they have thin(ner) finishes (they are reasonably thick on the edges where the relicing has involved knocking bits out, though - but in this case it's taken wood as well, so it's hard to be too scientific about it). And, like Philly, I can't identify any "plastic coating" going on on the bare bits of wood or the junctions between wood and finish (btw, "nitro" is a "plastic" :lol:).
A while back I suspected that the Roadworns don't have the equivalent of the old fullerplast thing going on - and this is to help with the relicing and later aging. Not so sure now, and, actually, I've stopped thinking about it - I just like playing mine.
Btw - I read that LP forum thread - what a load of old "internet discussion"! I read some luthier explain a while back (mebbe one of "ours" on here, mebbe not), he explained "why are you all bashing Fender for this? You HAVE to put something on before finishing, be it more layers of finish or a cheaper (and more effective) compound if you want a smooth finish... and they are ALL plastics!!!". Most folks, me included, probably regard "oil" finishes as different, but they are basically putting a layer of "plastic" on as well :lol:
The "nitro" part of Roadworns is all on the body, mind (in case you don't know yet), the necks are finished with, I believe, poly before relicing. Doesn't unduly bother me because I'm known to strip the backs of necks anyway - I just finished off what they'd started.
Certainly the RWs seem to be a much thinner finish than the fully finished Gibsons I own (the Fadeds don't have the thick top coat that the finished ones have). Also, in my experience, whatever Fender calls "nitro" is not the same stuff that Gibson call "nitro".
I do like the finish on the RWs (not so keen on some of the dings they put on it, but who cares? :lol:). I love how it feels compared to some of the more "indestructible plastic finishes" I have on other guitars. One of the reasons I like it is that it loves being polished. Brand new they look like dirty uncared-for things. Rub it down with a soft/dry cloth every time you play it, and suddenly in turns into a different beast - it looks old and has a satisfying glow/depth. Feels very nice once it's got its "glow" back (that they removed during the relic process, I guess).
Interestingly, my Gibson ES335 ("fully finished" in a satin trans-black), feels a whole load different. The satin polishes up with just touching it. It also feels a lot thicker and softer than what's on the Fender Roadworns. I have to admit it makes the thinner Roadworn finish seem "harder" and "colder" to touch in comparison. The 335 just feels so organic and "wood-like"(!) :lol:
I hear what you're saying about "I wish they came up with a way to make poly finishes thinner...", I used to think exactly the same. But I'm reaching the conclusion that this might not be what I'm actually after. I have a CIJ strat with a "poly" finish that appears to be much thinner and more flexible than the nitro guitars I have - but it still feels "harder" and "colder" to the touch than the Roadworns do...
I really do not know whether nitro vs poly physically affects the tone the guitar is capable of making. But I do know that what the guitar "feels" like in my hands affects how I relate to it and therefore what tones I'm capable of squeezing out of it. I used to think "thinner finish = better for me", but with the 335 I'm not so sure now. I think it's more to with what the surface feels like and how it reacts to my bare hands.
I'd actually like to get my hands on one or two of Twinfan's PRSs now, just to see what they feel like. I know he's got converted to "nitro" over the last few years. I think I have as well, and it sounds to me like the same vibe I'm experiencing with the 335 is close to what he's found. How we all express it will differ, but what it amounts to is "does this guitar make you want to play it more than the others"
So, with all this, back to where I started - "I'd recommend you try them". If it feels good for you, it is good, and don't worry too much about what "experts" on the web want to tell you (including me!) :D
