Barry:
Scale length is different from fret numbers. Two guitars can have the same number of frets and different scale lengths or vice versa. The scale length refers to the distance between the bridge saddles and the nut, though it is more accurately measured by taking the distance between the nut and the 12th fret and doubling it. The frets are then laid out in reference to the scale length. For example, if you measure the distance between the 11th and 12th frets on a Les Paul (24 3/4 scale length), and then measure between 11 and 12 on a Strat (25 1/2 scale length) you will find the distance is proportionately greater on the Strat. Scale length has an effect on string tension which has an effect on bendability and other factors. Many guitarists do pay attention to scale length. It is often the most important factor that makes one a Gibson man and another a Fender man (or woman, as the case may be. Gotta be P.C. this close to S.F.)
By the way, there is more to 22 vs. 24 frets than a place to put tiny fingers. It has an effect on where the neck pickup goes, which has an effect on the tone. Guitar design and construction isn't as simple as it might seem on first blush
Bill, tgo
