Koolau T100SP - Build a Custom Uke

Availability: Out of stock



Design Your Own Ko'olau Custom

Please note that you are not ordering a "In Stock" ukulele with this product. This enables you to custom order a 'uke with all the options of your choice. It then will be about 6-8 months before completion of your custom 'uke. Please contact us if you have any questions!

These are Ko'olau Tenor T100SP models. Just like the regular T100 but with top binding and purfling. How is the T100 different from the T1? Upgrade on woods, abalone rosette, & ebony fretboard and bridge are the main differences. Both come with Bone Nut and Saddle, Gotoh tuning keys, 100% Hide Glue construction, Nitro-Cellulose lacquer finish, a deluxe hard case and a lifetime warranty. On top of the SP binding upgrade, at the bottom of the page you can add the extra features you would like and order your own custom Hawaiian Ukulele!

2 great examples of the Ko'olau T100SP

One is a Cedar top with Koa sides and back and Koa binding. The second is a rare and beautiful wood known as Hawaiian mahogany (originally Cuban Mahogany). Here is a video:

These are hand built by Noa Bonk using the finest materials and utilizing the last 15 years of full time custom ukulele making experience. If you are craving some serious tone from a tenor, we guarantee this model will satisfy your uke dreams!

There are a number of reasons Ko’olau is a great choice for your ultimate ukulele. One reason is because in this day and age of mass production, Ko’olau Ukuleles are all handmade and setup by Noa Bonk. This ukulele is truly custom built by a master builder!

As you can hear, this model has excellent balance and sustain. For us, getting these instruments is a special thing. The feel of a Ko'olau gives you more freedom to just play and love it. As Zach said in describing Koolau ukuleles, "It just feels right".

The only problem with Ko'olau is trying to keep them in stock. Because of the small production nature of the custom shop, and their high demand around the world, this method of ordering is the fastest way to get one. We fit you into one of our build slots and you will have a Ko'olau in 2-4 months. This ensures you a beautiful and professional level ukulele. We guarantee you'll love it!

This is a tenor sized instrument and comes with a tenor hardshell case.

Custom Options

We start off with a Ko'olau T100SP. From there you can choose woods upgrade for highly figured woods. All wood will be different, especially with Koa. But we can request lighter or darker for you. (you can make a note under special instructions)

You have the choice of a Cedar or Spruce top. This is to many the ultimate tone woods for a soundboard. It increases volume and range. Some prefer the focused mid range that Koa has, and the Ash wood growing on our islands is another wonderful tone wood.

This model comes with the regular headstock but can be upgraded to a slotted headstock: [regular headstock

Here is an example of the Slotted Headstock.

Other options include a radius of the fretboard, and also an option for no fret markers on the fingerboard face. (still has side dots for your viewing).

The last big option is choosing a pickup system if you are plugging in.

Extra Options

The Herco HE360, is the included humidifier. You can upgrade to the more expensive Oasis Ukulele Humidifier (OH-18). This is suggested if you live in a low humidity area.(parts of California, Nevada, Arizona, etc..) including cold winter areas if you are heating the air most of the day and night. For more info see our Ukulele Care link at the bottom of the site

If you want a different set of strings you can buy them at the strings section and just note that you want us to change them in the special instructions.

No extra charge for Low G just write Low G under special instructions.
