What are the tone factors affected by which acoustic guitar parts?
The Guitar Neck
The most common woods used for neck construction are mahogany and, more recently, Spanish cedar. The neck's properties have an impact on tone because when you play, as much energy as possible needs to travel to the bridge to get those soundboard vibrations cooking. A very thin neck may be easier to play but your notes won't last or sustain as strongly compared to a thicker neck. It's about compromising. Gain one and lost another.
The Guitar Soundboard
The soundboard is equipvalent to speaker cone on a speaker. The soundboard responds to the vibration of the strings and air movement. In general, thinner the wood, the more responsive the soundboard is with these vibrations. But it needs to be thick enough to be strong and solid.The Bridge Saddle
Like the guitar nut,bridge saddles tend to be made from plastic, bone or synthetic ivory and have an impact on the string vibration and therefore sound of the guitar. Bone and synthetic bone are good for transferring the sound of your strings. Cheap plastics won't contribute much at all in comparison. On the whole, synthetic bone helps the tone sound a little brighter than the warmer bone. It's also more resilient so will need replacing less frequently.The Guitar Fingerboard
Yes fingerboard can affect the sound too. The radius of a typical acoustic guitar fingerboard usually measures between 18", significantly flatter than most electrics guitar. Most acoustic guitar fingerboards are made from rosewood, ebony or amble on top range guitars: ebony is denser and tends to sound brighter, which is good.
Guitar Made from Spruce?
Spruce is ideal for tops because it has a good mix of strength, clarity and dynamics, and it looks good. There are a few different types. Sitka spruce is the most common, found in the US and Canada. The lighter Engelmann spruce is found in the same part of the world and is seen as an upgrade from Sitka. German spruce is often used for classical guitars and is similar to Engelmann, while Adirondack is the most expensive, it responds well to hard playing while delivering balanced dynamics.Total Guitar
