Wow, thanks for all the response. I am rethinking maybe getting him a concert. I think we will head down to guitar center so he can try one on for size. If we do stick with a soprano I think we are going to go with the Koaloha long neck soprano, mainly because when given the choice it is the one he chose.
In response to some of the points raised:
"I agree with itsme. . . no ukulele, even a tenor, should be "too big" for a nine year old."
To all of you who said he could handle a concert or tenor I am sure you are right. The reason we became interested in ukes in the first place is their extreme portability and small size and we have only bought sopranos. He has played his travel Kala at the top of Halfdome and I have played mine at the top of Mt. Whitney. I want to keep it portable, but we will have him try out a concert before we make the plunge. Here he is on Halfdome in Yosemite:
"If it were my kid he get a Makala until he could play "while my guitar you know whats". but that's just me."
I have to admit that the uke is for me as much as it is for him, but he does already play very well. Some of you may have seen him play on stage at the sold out, "18th 'Ukulele Festival of Northern California" a couple of weeks ago. He has also played open mic at Mike DaSilva's shop, the last two Reno Uke Festivals and many others.
"hmm... this is too hard to decide...Why not get both? "
I would love to get both, the Kanile'a for me and the Koaloha for him, but it is really a stretch (and a lot of sweet talking to the wife) to just get one. We love our Kala's but I think you get to a certain point in your life where you stop and say, "no more particle board furniture in our house, time to go with solid wood" and that is where I am at with our ukuleles. Can't bring myself to spend a couple of hundred on another Kala, time to step up to a really nice uke that he can keep a lifetime.
"KoAloha is great and you will have a supremely marketable instrument to sell when in 2 years he decides he wants a strat."
Which ever one we buy I am sure it will stay with us forever. There are plenty of guitars in the house for him to pick up if he chooses (his brother plays guitar in addition to uke) but he still prefers playing the uke.
Thanks again for all the feedback, being honest with myself I think the reason I lean towards the Kanile'a is because Aldrine plays one and he has been such an inspiration to me.
