Ko'olau Adirondack Spruce Indian Rosewood Custom Tenor (CS 2249)

Picture and video specific to this listing. 

This is a new custom Ko'olau from Noa Bonk. The CS, or contemporary series, is their tenor design with a more rounded body and radius fretboard. 

For over 20 years Noa has been building fantastic ukuleles, but he never stopped refining his methods and the result is truly exceptional instruments like this one. This ultra-lightweight tenor has a big vibrant tone that has to be experienced. Corey gives us a review and sound sample.

Features include an Adirondack spruce top, or Red spruce, considered by many to be the holy grail in soundboards. This wood has the highest stiffness across and along the grain of all the top woods. This gives them the highest volume ceiling of any species, yet they also have a rich fullness of tone that retains clarity at all dynamic levels. This pairs perfectly with beautiful Indian rosewood sides and back.

The tone is strong and clear with wonderful depth. The sustain and overtones come in large part from the sides and back which are some of the nicest Indian rosewood you'll find. Noa was commenting on its exceptional tap tone. The body is framed off with super curly koa binding. This one also has the slotted headstock with Gotoh tuners.

There are many factors that make "the Ko'olau sound". One is that Noa only uses hide glue in his construction. This is a bit more time-consuming of a process but makes for a more crystalline, rigid bond (compared to Titebond) that tends to contract--rather than fill--the joint.   This leads to a crisper, "snappier" sound because treble is lost when joints get sloppy and hot hide glue demands tight joints and then makes them tighter.

It's protected with a perfect nitrocellulose gloss finish for the body and faceplate. The back of the Honduran mahogany neck though is a satin nitro finish for smooth sliding, and with the radius fretboard, it's extremely comfortable to play. Corey plays this one in a duet with Kalei.

The sound of this uke is inspiring and the level of meticulous craftsmanship is unparalleled. Get this amazing custom CS Ko'olau tenor and experience it for yourself.

Humidifier (Options at the "Humidifier Options" above)

This is required if you live in a low humidity area or if you use indoor heating/cooling, especially for areas with winter seasons or hot summers. If you are heating the air in your house, the air will become extremely dry.

Regardless of the outside humidity levels, the indoor humidity levels will drop dramatically once the air is heated. The same is true for air conditioning, usually not as drastic of a humidity drop as a heater, but it will remove a significant amount of moisture from the air as well. In either case, it is always a good idea to supplement with a humidifier that you store in the case with the instrument while not in use. This is usually a requirement by Ukulele manufacturers in order to keep the instrument covered under warranty.

In order to humidify the instrument, you will need a case for the humidifier to work properly and you will need to maintain the humidifier by refilling it as needed.

Other Options (Many found in the essential accessories above)
Another option is to switch your string set or change from low G tuning to high G tuning or vice-versa. Just add the strings you want and choose the restring option at the string listing.

Setup Options


Current Turnaround Time: Amount of time it takes before shipment-

Full Setup: 10-14 Days

Basic Quality Control: 2-3 Days

BASIC QUALITY CONTROL covers inspecting the instrument for any major defects that would have been missed by the factory and any faults in construction that could potentially damage or limit the functionality of the instrument over time. Any defective instruments are rejected and replaced.  We make sure that each Ukulele meets the basic standard for a brand new instrument and will be ready to play once you receive it. A final cleanup is also included after inspection before packing and shipment.

Full Setup - FREE for all Ukuleles $399 and over / $20.00 for Ukuleles from $300-399 / $30.00 for Ukuleles Under $300


-Overall QC evaluation: To find defects in construction as well as to get an overall view of the instrument and note the areas that need extra attention and adjustment during the setup.

-Saddle Adjustment: The height of the saddle is lowered to reduce the distance between the strings and the fretboard, making it easier to play than the factory setup, especially higher up the fretboard.

-Nut Slot Adjustment: The depth, width, and angle of the nut slots are adjusted to create a more comfortable playing experience especially on the lower frets.

-Fret Dressing: After adjusting the nut and saddle heights, high spots in the fretboard or uneven frets will potentially cause fret buzz, dead spots, or other unwanted problems. The frets are filed to create a more consistent level across the fretboard. We then crown the frets to return their rounded curvature back to the top of each fret creating a clear contact point for each string. We then smooth and polish the frets and condition the fingerboard to bring them back to new condition.

-Final Cleanup: We always do a final overall cleanup of the instrument to make sure it is in new condition and ready to play before it is prepared for shipment.

Rush Setup & Delivery - Additional $50.00
