Thoughts on my Mooncaster concept?

I just put a new neck on my Warmoth SG, so now I've got this Gibson-headstock neck just sitting around. I've been lusting after a semi-hollowbody for years, so I'm thinking of getting a Mooncaster body to pair up with the 24.75" conversion neck. The neck is mahogany, and I'm thinking a mooncaster with maple top and something warmer in the back (there's one in the showcase right now that's flame maple on korina). Then I'm thinking I will simply finish the body with Tru-Oil to bring out the grain and keep it simple. Thoughts on using Tru-Oil on flame maple and korina? Any issues with using this finish over the binding?

What do you guys think? Does this sound like it would result in a great guitar? I think the showcase body is already routed for humbuckers, but I'm also partial to P90s, myself. But electronics are easier to figure out later.

I don't see a ton of discussion of the mooncasters around here.
 
I have an idea - sell me the Gibson neck and get a Mooncaster neck for the...Mooncaster! I'm serious, why would you put a different neck on it? And as for the figured maple...man, I love the color. You can keep it simple, but my preference is to pop the figure.
 
I think it would be a good combination.  I've been toying with a Mooncaster design ever since they announced the Hombre.

IIRC, the Mooncaster can only be routed for humbuckers though...  Maybe its possible if you ask them.
 
Hum-sized P-90s and use the 3x3 neck. Of all the headstocks in the world to replace, the Starcaster/Mooncaster headstock is #1 to get rid of, and a classic 3x3 headstock will look as good on an archtop now as it always has in the past.

I'd advise an all-maple body, though, or at least alder or ash. Archtops made of warmer woods tend to be very muddy, even with underwound P-90s. This is why the vast majority of archtops are made using laminate maple, and woods like mahogany are used as a center block at most. The original Fender Starcaster, for instance, used maple for the body and the neck, had very bright Wide Range humbuckers, and was 25.5" scale, and it still wound up being an overall warm and smooth-toned guitar. Don't underestimate how much treble the archtop construction takes out of a guitar. It's very, very easy to make a balanced archtop warmer, but very, very hard to make a muddy archtop clearer.
 
I don't believe the traditional archtop/hollowbody characteristics apply to the Warmoth Mooncaster. Isn't it really more of an extremely chambered guitar with a thick contoured top?
 
A Gibson CS-336 starts out as a solid piece of mahogany.  And that guitar is simply amazing...

I'd be curious to know this myself.

Most Gibson and Gretsch (semi) hollow bodies are made by laminated wood (usually maple) so you are right, it's a different construction and it sounds different unless you believe that pickups are all that matters in an electric guitar.

Amazing or not this model resembles the ES line only visually.

Of course...  And I would guess that a mahogany Mooncaster would be closer to a 336.

Not at all. The Star/Mooncaster is pretty much the same routing as the most common semi-hollow archtops. An original Starcaster is between a standard semi-hollow and a full-hollow archtop, as the larger pickups required more wood to be removed, the bolt-on neck required less wood to be within the body itself, and the extended controls also demanded more room. The newer Starcasters retain a little more wood in the middle, and the Warmoth Mooncaster is closer to the modern Starcaster reissue than an original Starcaster.

The actual significant differences are in the wood and hardware choices, not the construction itself. An original Starcaster used laminate maple for the whole outer body—typically just 2 laminate layers for the back and top and 3 for the sides—with a block of alder for the center, and a one-piece maple neck with a very light single truss rod and micro-tilt system; the oversized flatmount bridge and Wide Range pickups also took up more space, as I mentioned before, and the materials used for the bridge in particular really helped retain some brightness. The recent reissue uses 3-layer laminate wood all-over, a tune-o-matic and stopbar bridge, quartersawn maple for the neck and a much heavier-duty dual truss rod and 4-bolt mount. The Warmoth Mooncaster saves even more of the center wood by using the more common, smaller humbuckers, and the wood is whatever you like, though they do insist you have a laminate top of some form; liek the reissues, the tune-o-matic and stopbar combination typically gives you a little less treble retention compared to the outsized flatmount of the originals.

For comparison, the vast majority of other semi-hollow archtops use laminate maple of various kinds, usually with a maple center block, typically around the same size as the original Starcaster had. (Reissues'/Mooncasters' blocks being a tiny, tiny fraction larger.)

The upshot is that the Warmoth body should, in theory, carry very fractionally more treble than a reissue Starcaster, assuming you were to use maple for the whole guitar and you gave them comparable electronics and hardware. An all-maple Mooncaster should—again, in theory and assuming you equalise everything as much as possible—be very fractionally warmer than an original Starcaster.

With a 25.5" scale maple neck, I would expect a mahogany-bodies Mooncaster to remain a little snappier than common set neck, 24.75" scale archtops, but with a 24.75" scale neck—let alone a mahogany one—the tone isn't going to be much different from an ES-335 style of construction. The bolt-on should mean the neck pickup has a little more treble to it, but the bridge pickup will be about the same; remember, the bridge and bridge pickups on most archtops are rooted firmly in a solid block of maple, not alder like a Starcaster or god-knows-what with a Mooncaster.

So, if we were to take a Mooncaster body made of mahogany with a maple laminate top, and put on a 24.75" mahogany neck, you're going to get a much warmer tone than any archtop you'd usually handle. The neck pickup may—may—retain similar clarity to an maple-bodied archtop, but I wouldn't want to bet on it, and you can say goodbye to any treble from the bridge pickup, if you're not severely compensating with your electronic choice. A mahogany back, sides, and middle is a very different tone from a ES-335's or Dot's laminate maple outer and solid maple inner.

For reference, there is an archtop—sort of—which uses mahogany for the outer and middle of the guitar: the Epiphone 'Kat' family. They use a 2- or 3-piece solid mahogany body, routed out like a Thinline Telecaster, and then have a top added which is a mahogany & maple laminate, with an additional maple veneer for some finishes. Their bodies are a little broader than a Les Paul but smaller than a Dot, Casino or ES guitar, and they are a little thicker, at just over 2" deep. They use a set-in, 24.75" scale, 3-piece flame maple neck and rosewood fretboard. The 'WildKat' model has a tune-o-matic and bigsby, with P-90 pickups, and the 'AlleyKat' model uses a tune-o-matic and stopbar, with humbuckers.

In terms of overall construction, it is those Epiphone Kat guitars which are closest to a mahogany-bodied Warmoth Mooncaster; both have the slightly looser resonance of the simpler, less heavily-laminated construction, both would have mahogany for both the outer construction and the center block, and their default hardware and electronic layout is more similar. The Mooncaster will still have a larger hollow area, though—it's still a broader body style—and, though one is a bolt-on and the other is a set neck, the rigid 3-piece maple of the Kat guitars would balance out the mahogany used for this hypothetical Mooncaster.

And I can tell you right now that even the brighter 'WildKat', with its bigsby and P-90s, is one of the warmest, thickest, smoothest, and muddiest guitars you will ever play. A Mooncaster with a similar degree of mahogany dominance is not going to have any treble to speak of, without winding some severely bright pickups and cutting out some of the controls.

That's a very, very different type of guitar to any other archtop of a similar appearance. The body is significantly smaller than ES-335s/Casinos/etc, and it has so little wood taken out of it that it has more in common with the '72 style of Fender Thinline, or the Epiphone Florentine Les Paul, than even a semi-hollow archtop, let alone a fully-hollow body. Even the Epiphone Kat guitars which I mentioned above have more in common with a standrad archtop than the CS-336.
 
Thanks for the fantastic, detailed reply (and to all the others who have replied)! This is exactly the type of info I wanted to get here!
 
Indeed, that was very informative. Gonna have to read it again (and probably again) to figure out whether or not it's a body I'd like to use.
 
No need for apologies; it was very informative. There's just so much info there, esp. w/respect to comparisons with other semi-hollow bodies, that it bears repeated reading.

Were I to do another Warmoth build, the Mooncaster would likely be my choice, but I wanted a better sense of the body construction (note that Warmoth says it is hollow, not semi-hollow) and how wood choice might factor in w/respect to sound. Your post gives me the beginnings of an answer, for which I am grateful.
 
Interesting post, Ace. I'd assumed that W's Mooncasters were built like their other hollow carved-tops. They don't provide a product page for the Mooncaster, but the hollow VIP info states that they have a '1-3/8" thick core' and a '3/4" Double Laminate Bookmatched Top'. My interpretation of this is that a sectional view would be something like this:

Is the Mooncaster different, or are my assumptions about the other models wrong?

Humbucker sized P90's?

I love the Seymour Duncan Phat Cats, although I hvae a Pearly Gates in the bridge with the Phat Cat in the neck.

Lindy Fralin and Gibson make good humbucker sized P90s as well. I think its a great idea for a Mooncaster build!

And I also second the Mooncaster neck ;)
 
Yup, that's how they do semi-hollow construction, and that's the overall form of nearly all semi-hollow archtops.

Generally, the distinction between a semi-hollow and a fully-hollow body is a semi-hollow has a mass of wood running through the middle, while a full hollow either has no wood in the middle, or only has the bare minimum amount of wood needed for the bridge to be secured. Some semi-hollows are made with pillars of wood throughout the body, instead of a central block of wood, but these are pretty rare and I'm not aware of any such designs really lasting, other than the Yamaha RGXA2, which is really a hollow super-Strat.

Some people will refer to a guitar as simply being 'hollow', regardless of if it's a true hollowbody or a semi-hollow. Of course, some people also consider chambering to be the same as semi-hollow. Most people stick to the traditional usage of each term, but it's not surprising when a company misuses one of them for marketing purposes. Same problem as people mixing up vibrato/tremolo, split/tap, etc.

So yes, the style of hollowing that the VIP uses is the same as the Mooncaster uses, which in turn is the same as the Epiphone Kat guitars, Fender Thinlines and Gibson Midtown. Warmoth is starting off with a solid body and cutting out all the wood to form the hollows, leaving the centre intact. This is different to most archtops—including the Fender Starcaster, both original and new—where the middle block and the sides/back/top are all seperate pieces of wood, shaped independently and then glued together.
Tonally, this shouldn't make much of a difference, other than that the Warmoth/Kat/Thinline/Midtown method means you're more likely to be using solid wood for the back and sides, while the more common semi-hollow construction methods mean you're more likely to be using laminated wood for the back and sides. Laminated wood is more stable and much stiffer, which should mean more treble is retained, but some people feel that treble is lost through all the layers and glue. It's the same argument as 1-piece bodies vs 2- or 3-piece bodies. Some people think there's a difference, others don't; there are so many variables within each guitar that it's impossible to truly pit laminate sides vs solid sides.
This is why I mostly stick to just worrying about what the wood species is, because we know the difference between mahogany and maple. And, regardless of whether the back and sides are carved out of solid wood or made of laminated pieces, the top is always a laminate anyway, and the top wood is what seems to make the most difference.


Dubious disclaimer: I base this on my own experience playing these guitars, and reading into the history of the guitars. I don't have time to actually subject every kind of body to critical x-raying and stress tests, so there's no pie charts and bar graphs and wavelength studies to illustrate any of this. Other peoples' experiences may differ, tastes vary wildly, and of course there's more to the sound of an electric guitar than just the wood.


edit: forgot to attach. Image of a typical semi-hollow archtop being constructed. You can see the laminated and ribbed sides which have been shaped separately from the center block. You can see how this differs from Warmoth's VIP/Mooncaster construction style.

edit 2: I just remembered that Warmoth also does/did make the L5 body style, as well. For the record, I don't know how they are/were constructing that one, as that's one of the body styles I've never gotten my hands on.
