▪ Freeman has made a number of guitars with varying combinations of off-center soundholes, graduated body depth, rolled-over edges, and adjustable side ports. He gives us his thoughts on how these design factors interact and how they advance his quest for a more erognomic steel string guitar.

▪ Do you believe that soundports on the side of a guitar make a difference to the sound perception of the guitarist? Do you believe they don’t? Either way, you should consider the facts presented in this article. It may change the way you build guitars, but it won’t give you more faith in the hearing of humans, even of professional musicians. With 1 photo and 3 charts.

The “Corker” Guitar: A Sideport Experiment

2008

Alan Carruth                                                                                           

▪ Carruth built a classical guitar with many ports cut in the side. By closing the ports with corks in various combinations he tested the usefulness of sideports and tried to establish the physics behind their use. Though this guitar did not make a believer out of him, he admits that his results are somewhat inconclusive. With one photo and a slew of charts and figures concerning the air modes of his guitar with various sideports open.

His article includes personal background, developmental work on his sideported instruments, and construction techniques. With 3 photos.

▪ The author found that a sideport (hole in the side, in addition to the front soundhole) in his guitar changed its voice in an undesirable way. Adding a bass reflex tube to the hole returned the guitar to a tonal range he liked. He remains luke warm to the benefits of side ports. With 5 photos.

▪ Ruck has been adding sideports (holes in the sides, in addition to the front soundhole) to his classical and flamenco guitars for many years and is a strong advocate of their advantages. The incidents that led him to incorporate ports are very interesting. He mentions Roger Thurman and Augustino LoPrinzi. With 1 photo.
