acoustics are a very personal choiceThe Bottom Line Buy what makes you happy!
I have been mostly an electric guitar player for the last 25 years so if you want to hear from a true acoustic expert, I suggest looking at the article written by jmaroli. I just want to put my 'lectric spin on the matter. I used to think wood made a difference in tone in an electric guitar...until my two younger friends introduced me to their 7 foot amps that said, M...A...R...S...H...A...L...L.
Those amps could make a styrafoam guitar sound like a Les Paul or something good enough to give us a $235.00 noise ticket being just on the other side of a police department in a city that makes Dr. Laura look liberal. My next ticket will be over $1,500.00 if I get caught...fifteen bones, well that is what I consider the high end of buying an acoustic guitar.
High end acoustic:
This is the category that I call anything better than the standard Martin D-18, the basic good quality guitar which Elvis used to write his songs on. The tops of these high end guitars are made of solid spruce and the back and sides are of solid mahogany.
Guitars in this category are at least as big as the standard dreadnaught and sometimes bigger. Martin's high end guitars include the D-28, D-41, J-40, and the legendary D-45. Other guitars in the over fifteen hundred dollar category include Santa Cruz Guitars, Taylor Guitars, Lowden Guitars, Larrivee Guitars (not sure about spelling on that one), and Gibson Guitars.
Other woods found on high end instruments could be Koa, Indian rosewood, and Cedar...all solid and high grade. If you are lucky, you may even find an acoustic made with Brazilian rosewood but the last American who got a large amount of it was a guitar builder friend of mine who has a Brazilian wife and sells the wood to some of the above makers I mentioned.
A high end guitar that isn't played by a famous person or a one of a kind special custom shop instrument usually can go up to four or five thousand dollars. A non wood high end instrument which has low action and is the best for an electric cowboy like me is the Ovation guitar or Parker Fly guitar which are definitely high end.
When we got the noise ticket, my friend just wanted to toss his $600 dollar Fender Stratocaster out the window and take up being a librarian and use his well earned English degree from U.C. Davis. Six bones is what I call a good figure for a moderately priced acoustic guitar.
Mid-level acoustic:
A good starting point are the mahogany 00 and 000 Martins which are in that price range. Fender's high end acoustics, Ibanez high end acoustics, Yamaha high end acoustics, and Takemine high end acoustics dominate this range starting at six hundred to going up the fifteen hundred. This is the most common guitar which, while being acoustic, is often set up with a Fischman type saddle pickup and is electrified. More rockstars use these mid-level guitars than any other acoustic due to the amplification and cutaways often found in acoustics in this price range.
More often than not, only the top is solid spruce and the back and sides are laminated but there are exceptions out there to that rule. These guitars have necks which are just as good as the high end necks and have an acoustic sound just below that of a top of the line instrument. Many electric players like me cannot tell the difference between an all solid acoustic versus an acoustic with just a solid top. It is the loud and rich sounding solid spruce or cedar top that I pick up on.
My friend who got the noise ticket did not charge the other band members since he let in some teenage boys after practice and let them turn up the Marshall full stack to eleven, not ten...eleven. It must have shook the cops like Ted Nugent setting up in their washroom. My friend makes a small living and that $235.00 noise ticket is something he still brings up six years later. Nw $235.00 dollars would have bought a good low end acoustic.
Low end or beginner acoustic:
Martin has a low end acoustic under their brand name Sigma, Fender has a lot of offerings, Gibson has their Epiphone label, Ibanez has a few, and Yamaha has their share of the beginner market.
These guitars usually do not have cutaways, electronics, or any form of solid wood. The tops are spruce but laminated and the sides and back are laminated mahogany if you are lucky. The usual wood is nato or natto and laminated maple has been known to be used.
At one time, the action on these instruments used to be hideously high. But now due to computerized manufacturing, the action on these low end guitars are the same as one any guitar you will find in the store. Sitting down with a low end instrument is not bad since the volume is deep and rich.
It is when you stand five or ten feet away that one notices that the sound diminishes and there is little or no projection. This is due to having a laminated top.
If you have between two hundred to six hundred dollars and want a good low end guitar, don't go after the name on the headstock, go for an instrument that feels right which has a solid spruce or cedar top.
It is better to buy a three hundred dollar Epiphone on sale with a solid top than it is to buy an Epiphone at the same price with fancy binding and a deep cutaway. The solid top will improve with age greatly while a laminated top will only slightly improve over the years.
In defense of laminated tops, there were a lot of Takemine low end laminated top instruments made in the 70s and 80s which have aged extremely well and do sound like a good solid top guitar. So these suggestions are just very, very broad outlines.
And back to getting that solid top three hundred dollar Epiphone over that cutaway model with a laminated top. If you are a lead guitarist like I used to be, that cutaway is of the highest importance when playing beyond a high F#. It is just the solid top which will give you the better sound over time.
Conclusion:
So that is my electric guitar player's rough guide to buying a high end, mid-level, or inexpensive acoustic...and oh yeah, do not crank up a Marshall full stack next to a police department.
