As Peter knows from repairing fingernail dings outside the golpeador on my Ramirez guitar, the golpeador on that guitar obviously isn't large enough to avoid damage when I play. I was surprised when I first noticed those dings, because I haven't been aware of tapping that far out from the strings.
Someone posted this on Foroflamenco a long time ago: "
When the wear on the golpeador is only in a small area as is the case with Ricardo's it indicates a skilled player with refined technique." I don't agree with that statement. There are many styles of flamenco playing. Golpes are used in different ways in those various styles. Even within the same styles, flamenco playing can range from very soft and slow to extremely hard and fast. Highly skilled players play in all those different ways. When the wear on a golpeador is limited to a small area it indicates to me that a player probably plays a limited range of styles and nearly always plays them in the same uniform (boring) way. That type of playing is not typical of flamenco. Flamenco tends to be fiery with quick and often unpredictable changes in tempo, technique and style. The resulting unpredictable-contrasts are important to making flamenco seem fresh and exciting even though listeners have heard countless soleares, bulerías, alegrías, or whatever, before.
It seems to me that there are three primary considerations related to golpeadores:
1) Ideally a golpeador should be large enough and strong enough (and/or thick enough) to avoid fingernail dings in a guitar top.
2) Ideally a golpeador should not negatively-affect sound quality, which may mean that a guitar with ideal sound quality wouldn't have one. (I don't know whether that is true. I think it is theoretically possible to design golpeadores that would improve sound quality.)
3) Ideally a golpeador should improve or at least not negatively-affect guitar appearance, which depending on personal judgment may mean that a guitar shouldn't have one or, if it does, that it should be decorative. However, not having a golpeador violates Consideration 1 and having a decorative one (such as one made of wood) may violate Consideration 2.
I would be interested in knowing how much Peter has found that golpeadores of different sizes, shapes, thicknesses, and materials affect guitar sound characteristics. In addition to the general alternatives of using plastic or wood, there are many types of both plastics and woods that could be used. Some have interesting characteristics. For example, Polymethyl Methacrylate is a transparent thermoplastic that is so hard that it often is used as a replacement for glass. It is sold under a large variety of trade-names, including Plexiglas, Acrylite, etc. and is commonly known as acrylic glass. I am curious to know whether golpeadores have been (or often are) made from it. Because it is very hard and stiff, a thin sheet might act as an efficient transducer to convert high-frequency vibrations to sound waves, so that instead of muffling high-frequency sounds as soft materials on guitar tops do, it might enhance them.
What about using thin glass? Has that been tried?
What about spacing a stiff golpeador slightly above a guitar top, instead of sticking it directly to the top? Would that result in better or worse flamenco sound characteristics? A golpeador mounted that way could be made easy to replace without guitar-top damage. Would a stiff, relatively-small golpeador spaced slightly above a guitar top and attached rigidly to the bridge function as a high-frequency "tweeter" that would increase the intensity of high-frequency sounds while having negligible affects on other frequencies?
I think Peter should make thousands of guitars with all the possible variations so we can learn what is best!
