Mahogany is a lovely wood to work with. Old-timers maintain that the quality of mahogany isn't what it used to be, and I am forced to believe them. Supplies today vary widely in hardness and density. Some mahogany is stiffer and heavier than other samples. Some mahogany guitar sets seem almost fluffy and floppy by comparison. Most mahogany is plain, yet pleasing to look at. Sets demonstrating a ribbon figure are prettier, but tend to ripple across the grain during bending, though the rippling can almost always be sanded out without compromising the guitar. Straight-grained mahogany can be predictably bent into a tight cutaway without breaking. Tool marks and sanding scratches are easily removed. Mahogany is a dream wood.
