The 5 Series uses a thinly applied high gloss finish to bring out the true beauty of the wood while being thin enough not to interfere with the natural vibrations and tone of the woods. The thinner finish helps the tone and lets you hear more of the wood in the guitar, instead of a thick plastic soundng finish. Parkwood is concerned about tone first, looks and everything else is secondary. This hard and durable finish will protect your guitar for years.
