Beansprout was started in 2007 by Arron Kiem with Heidi and Rob Litke in Broomfield, Colorado and in 2010 Aaron became the sole owner.
Under this branding over 100 instruments were made before Aaron moved to Oregon to work for Mya-Moe Ukuleles in 2011. While at Mya-Moe Beansprout was on the back burner with Aaron only using it for the occasional Banjo, and Aaron worked on the 2000+ instruments that Mya-Moe put out while he was there.
In 2018 Aaron decided to work on his own again, (well with at least the support of his wife Nicole too), still in Oregon, making Concert, (but he actually like to call them Alto), Tenor and Baritone Ukuleles, Concert and Tenor Banjoleles, plus a Baritone he calls the 4 string Banjo and 5 string Banjos using local and reclaimed wood. Occasionally he makes a round body Soprano Ukulele from offcuts he calls the Scout.
Nothing to do with the Richter Mfg. Co. Scout of the 20's
A member of the Big Island Luthiers Guild he is based in Kainaliu on the Big Island where he runs a music shop called Kiernan Music Co.
He started in the 1970’s as an apprentice in New York learning to make Archtop Guitars; which are still his primary focus. In 2006 he started making, initially traditional Tenor scale Ukuleles along with his son Derek Kiernan, (who learned luthiery from his Dad and spent a few years at Goodall Guitars too), and calling the output K Side Ukes. They now make other more contemporary looking Ukuleles as well.
He is based in Funai-gun, Kyoto Prefecture Japan. He started in luthiery studying with Shiro Tsuji in 1978, and after a period of being a musician and travelling the world he started his own workshop in Ayabe, making Guitars in 1991, moving to the current location in 1997. In the intervening years he has added an number of folk instruments including the Ukulele to his catalogue.
The current Ukulele range is long neck, (Super) Soprano, Concert, Tenor and Baritone scale in a variety of woods. The non-traditional shaped one he does in Concert and Tenor only and I run into a lot of difficulty on the name he gives it as the translators keep translating it a "Mumps" (?? I do hope this is correct). He has made archtop Ukuleles in the past based on his archtop Guitars and he gives all of his instruments a lifetime, (his, I presume), warranty.
Originally a musician he took up luthiery in 2009 to supplement his income, (I believe he teaches Ukulele too). He makes Concert, Tenor and Baritone scale Ukuleles plus a kind of Pineapple he calls the Rice Ukulele, (don't know why but I have also seen resonator versions of this), and some Banjoleles under the branding Ka Lani The Strings.
Based in South Africa he started out making Violins but now makes mainly Guitars. His work is fairly innovative as he says he doesn't like making slavish copies of other instruments and he has made some Mandolins and Ukuleles too. In addition to making instruments he also teaches luthiery.
