You mean the Totnes school of guitar making down in devon!
It,s a lot more than just being tutored for a few days while you put together the bits to your new bass, they teach you the whole deal from solid bodys thru to building acoustics as well as neckmaking,fretting,inlays and so on.
I,ve not done their courses but I,seen some of the work done by ex pupils at guitar shows over the last few years and they are very impressive.
It,s probably a bit overkill on the education front if all you want to do is just build up a couple of instruments yourself but definitly the way to go if you are looking to make a career out of it.
