Frets.com is a free site, with no commercial interest, that Frank Ford created a few years ago, to share what he learned in music and instrument, with the hope that others will share their knowledge as well.
You can get some nice ideas in this site such as how to transform an old gym sock into a great cover for a machine handle that tends to go slippery with use. And it is all shown in pictures, so you can easily understand and follow the instructions!
There is also a section called “of interest of players” where very useful advice on general maintenance of instruments is given, as well as information of instrument setups, accessories, acoustic guitars, jazz guitars, banjo , mandolin and everything you musicians out there need to know!And if you enjoy this site, and you find it useful ou can help it to continue running by donating bit of cash or by purchasing a copy of frets.com on cd-rom.
