IMPORTANT PRECAUTIONS WHEN BUYING A GUITAR:
You should obtain ALL the information we give in our data chart when buying from a private owner or a broker. If not, beware! This is an example:
You should get some additional pictures when buying a new guitar or a vintage one:
A picture showing the neck relief, and how straight the neck is.
A picture showing the bridge height. If the bridge height is less than 15mm, be suspicious. A good bridge height is 18mm or more.
A picture showing the neck angle in relation with the top of the guitar.
A picture showing the deflection of the top at the bridge level. A slight deflection is acceptable, but a collapse is not acceptable. The seller should place a rule on top of the bombe and the picture should show that the top is higher that the sides and give the measured difference.
Pictures showing the condition of frets.
All information and all dimensions are important, and we would like to draw your attention on some very important dimensions.
The action at the 12 th fret. The right action is the action when there are no buzzes for your type of attack when comping or playing single notes. This is the right way to measure it.
Press the low E string between the zero fret and the 1 st fret. Measure the height between the top of the 12 th fret and the bottom of the low E string. A low action is 2.8mm, a very high action is 4.5 mm. An optimum action for a great sound and playing comfort is 3.6mm.
Press the high E string between the zero fret and the 1 st fret. Measure the height between the top of the 12 th fret and the bottom of the high E string. A low action is 2.5mm, a very high action is 4.2 mm. An optimum action for a great sound and playing comfort is 3.3mm.
NEVER buy a guitar if you cannot return it within a reasonable trial period, let’s say up to 10 days. ALWAYS show the guitar you bought to a good luthier. Put new strings on once you get the guitar.
