Knowing how to choose the right guitar and how to identify a bad one, will save you from countless headaches, not to mention finger aches.

Acoustic guitar bodies come in basically the same hourglass shape, with some variations, but they do vary in size, colour,wood-type, style, and extra features. You can even buy an acoustic guitar so small that fits into a hiking backpack.

Guitars come in a very wide range of prices, but when it comes to instruments, in general, you get what you pay for, especially when you buy new. There's a real difference between getting a bargain on a site like eBay and buying cheap.

But whether you buy new or used may be determined by many personal factors including your budget, and each has their own pros and cons.

Buying new, gives you a warranty and, hopefully, a return period,if for some reason you're not totally satisfied with your purchase, or something goes wrong.

Under 'usual' circumstances, a used guitar can usually be purchased cheaper and has already gone through its "break-in"period.

Commercially built guitars are usually mass manufactured."Custom-made" guitars are exactly that. They are custom built and tailored to your specifications by a highly skilled guitar maker.

Prices for a custom-built guitar vary considerably, depending on the skill level of the crafts person you contract the job to, but,as a rule, they are generally quite higher than a commercially built guitar of "similar" quality. Each custom built guitar is unique and therefore hard to compare in price to a commercially built guitar.

For the "Techies"

Understanding some of the parts of a guitar will definitely help you when it comes to the Pre-Purchase Check-list.

Body

This is the part with the sound hole in the front. It is where the strumming is done, and it can vary in size. The actual size, shape, type of wood, coating, and general build of the body also affects how the guitar will "sound", whether it's a rich and warm sound, or a thin and 'twangy' sound. The body tends to be the part that also gets scratched, damaged, and generally banged-up the most.

Neck

This is the long piece extending from the body and ends at the 'head' of the guitar where the 'Tuning Heads' are, also known as 'machine heads'. The strings travel from the 'Bridge' on the body, across the sound hole, along the 'Fret Board', which is attached to the front-side of the neck, and finally arriving at the tuning heads where they are wrapped around tuning posts. The tuning heads are then turned by hand, which then turns the posts,making the strings tighter or looser, thus affecting their 'tuning'. Necks tend to warp and twist if not looked after, or if the guitar is left propped against a heat source.

Bridge

The Bridge is normally located on the front of the body,by the sound hole, and on the side of the hole opposite to the neck. The strings are usually fed through the bridge first before they cross the hole and travel up the neck to the tuning heads.The bridge is like an anchor-point for the strings. Metal bridges are best, but on most acoustics they are either hard plastic or wood. Bridges have a tendency to crack and split over a long period of time.

Fret board

The fret board is glued to the front of the neck.This is the part you press the strings onto to make chords or play individual notes. Because it's glued on separately, a fretboard can be made of a wood that's different from the neck.

The strings travel over the fret board and the distance they are above the fret board makes a difference to the playability of the guitar. If the strings are too far above the fret board, then they will be hard to press down, making the guitar hard to play.

When a beginner plays a guitar, initially his or her fingertips are very soft and need to be hardened. A guitar with the strings too far above the fret board, also known as having a 'high action', will cause the player's fingers to hurt so much that they are likely to put the guitar away in discouragement and possibly stop playing altogether.

Strings

Acoustic guitar strings, come in a wide variety of 'flavors'. They can be made out of nylon, brass, steel, or a combination. Nylon strings are usually only found on Classical guitars and Student guitars, because they're easier on the fingertips. They have a rich, warm sound to them.

Strings sets come in different 'weights', or sizes. Strings that come from a package marked 'Heavy' are usually quite thick in size and sound "beefy". Strings that are light, or extra light,are very thin and usually have a brighter sound to them, but are also quieter sounding than heavy strings.

String choices are purely personal taste. Light strings are easier to press than heavy strings but also sound quite different. The more often strings are played, the dirtier they get. If a cloth isn't run over and under them, from time to time,the sound becomes very dull

Pre-purchase check list

• Before you buy a used guitar, cost compare against the price of a new one, unless the guitar is quite old. You could also compare its used price to other used prices by going to an online auction and either searching for the same or a similar guitar.
• Check the overall condition of the wood for cracks, scratches, splits, dents, chips, etc.
• Also check the lacquer finish for cracks and splits.
• Check the neck/fret board for warping and twisting. You can do this by holding the guitar flat on its back, with the sound hole facing upward. Bring the guitar up to eye
• level, with the neck running away from you and the edge of the body almost touching your face. Let your eye-sight skim across the front of the body and down the fret board. You should be able to see if the neck is twisted or bowing.
• Tune the guitar, or have the seller tune it for you.
• If you know how to play about five or six chords then play them. If you don't know how to play, ask the seller to play them for you. This check ensures that the neck of the guitar is not warped, even though you couldn't physically see it. If the neck is warped, and the guitar is properly tuned, then some of the chords will sound good, but others will sound as though the guitar is not tuned. If this happens, check the tuning again. If it persists, then don't buy the guitar.
• Check the bridge of the guitar. If it's made out of wood or plastic, make sure it's not cracked or splitting. The bridge needs to be rock solid, as a lot of pressure is exerted on the bridge by the strings.
• Check the tuning heads. Do they turn easily, or are they very stiff and hard to turn. Even with the high tension of the strings, a quality guitar will have tuning heads that are fairly easy to turn.
• Check the 'action' of the guitar. Are the strings a fair distance from the fret board? Are they easy or hard to press down at various points on the fret board?
• If you are buying the guitar for yourself, and you know how to play, even if you're a beginner, then play the guitar.
• How does it feel?
• Is it easy or hard to play?
• Can you fit your hand around the neck/fret board comfortably to play chords?
• Is the guitar a comfortable size and shape for your body? Is it easy to hold?
• If you plan to play standing up, ask for a guitar strap.
• Do you like the sound, the colour, etc?
• If you don't play,have someone else play it for you so that you can judge what it sounds like.

Where to buy?

Buying a guitar from a physical retail music store allows you to 'test drive' the guitar and ask more questions up front. Buying online from a site like eBay or a catalogue may bring you more cash savings.

No matter where you buy your guitar, if you know what to look for, and spend a little extra effort in your search for that 'perfect' guitar, not only will your fingers thank you, but also your ears, and all those who will come to join you around the campfire, or even go to see you in concert.
