I am here suggesting what NOT to Buy...
I have observed many new to CG players that are discouraged when they buy their fist CG. They follow the manufacturer' advertisement and reputation in the market place without the opportunity to test the instrument. When I started to learn the CG that is exactly what i did and I learned these very pertinent lessons...
1- Not every player have the same size hands and finger length... Meaning the guitar scale length is a valuable guide to help choose the right "fit" instrument for any new to Guitar player.
"Scale Length" of the guitar is NOT the overall size of the guitar as often seen in advertisement of guitars like... "full size", 7/8, 3/4,1/2 -sizes.
" Scale length" is the distance of the strings from the NUT to the top of the SADDLE - THE WHITE PIECE INSERTED INTO THE BRIDGE OF THE GUITAR.A so called "full size" classical guitar is built with a Scale length of 650mm, anything less is a "short-scale" and anything longer is a "Long scale" guitar.
2-The distance separation between frets on the fret board are determined by this designations.Players with short length fingers / small hands could benefit from a short scale instrument. i have owned and played all types of scales and when I play the full 650mm scale I tend to feel "finger fatigue" after a period of time - about 50 minutes of playing. My preferred scale lenght CG is between 630 and 640mm - I now own one of each and it makes a Lot of difference in my comfort and skill performance of any musical piece I am trying to play.
3-You can find this information on scale length on quite a few guitar sellers web sites. If not listed call them and ask.It will pay -off in truly enjoying your play-ability and progress in your studies.Good Luck
