V... Luthiers (21st C.)

Federico (Fred) Vento is based in Hilo, Hawaii. He use to work for Goodall Guitars before setting up his own shop some time before 2008. He makes all the standard scales, including Baritone in three levels of decoration he categorises as S, D and A he will also do some semi custom work beyond the standard décor. He makes Guitars as well as Ukuleles and puts a big V on the headstock as a logo. 

Based in Peterborough, Ontario he has been in business since 2012. He is largely self taught and makes a number of instruments like Guitars, Mandolins, Harps, Dulcimers and even Kalimbas (a kind of thumb harp). With the chordophones He mainly uses a body shape inspired by the golden ratio and looking very organic, these and often come with an unusual nautilus like bowl backed too and he calls this design "Roots". In some instances his wife adds some leaf motif decorations by burning the wood with a soldering iron. In his catalogue he includes a 15 inch Concert, a 17 inch Tenor and a 20 inch scale official Baritone Ukulele; plus a Uke Bass version he calls "the Bud". Beyond these he also has a 21 inch and 23 inch, (Tenor Guitar?) scale model that he calls "the Root" and just describes as a 4 string instrument, (or 5, as he does a 5 string version too). With this you can have nylon or steel strings and he lists a wide range of tunings including Ukulele ones. For the Buds he fits a piezo pickup to all models for the others it is an option. I have seen an oval bodied Baritone Ukulele he has made and he called this body shape "the turtle" rather than the nautilus shaped "roots"

From Kea'au, Hawaii and advertising themselves as TV Wood Craft this is a father and son luthier workshop, plus some students, (because they teach Ukulele making as well). The father is Gerard Vincent and the son and main luthier is Thomas Vincent. 

They make predominantly Tenor Ukuleles and other wood craft items like jewellery boxes but not other musical instruments.

From Buenos Aires, Argentina he is a maker of Ukuleles, 4 string Cuatros and other small South American chordophones like the Charango and the Cavaco; I have not seen Guitars in his catalogue though? He has been in business since before 2010 and has a website that doesn't appear to work, He started other on line sites but they all seem to have been abandoned since 2013 so I am not sure if he is still in business? On one of the sites it suggests that he may teach luthiery as well?
