Many beginners simply don’t realize that there is a range of adjustability on most guitars and basses. The first thing to consider is string gauge or thickness. Traditionally string gauges are expressed in thousandths of an inch. For example, the high E string in an electric light set typically measures .010″ (ten thousandths of an inch), and is usually called “a ten”. A set of electric light gauge strings is referred to as a “set of tens”. The beginning electric guitarist, however, will probably want an extra-light gauge set, or a set of nines (high E string .009″). This will ease the early struggles of pressing the strings down to the frets. Most electric guitars are shipped with extra-light strings for just that reason.
Acoustic guitar string sets are gauged a little thicker than electric sets, and many guitars come with strings that are too heavy for the beginning player. Look for a set of extra-light acoustic strings with the high E no heavier than an eleven (.011″). Classical guitars are equipped with nylon strings and are easier to press down to the frets. If the strings on the classical guitar seem too tight, try a set of light nylon strings.
Bass guitar strings also come in different gauges, and today’s student basses are usually equipped with light strings.
One thing to remember is that as your hands become stronger and you begin to play with a lighter more expressive touch, you can go up to the next heavier gauge strings. This will give you more sound from the guitar, as the loudness of the tone is directly related to the mass or thickness of the strings.
