Here is an instrument that is just hard to believe; how does Peter Marreiros the master luthier of Cornerstone Ukuleles build such a beautiful ukulele with such commanding sound? This is a labor of love, for sure.

*NOTE - This is a prototype and was displayed at the Los Angeles International Ukulele Festival. I would consider this instrument in excellent condition but there are some light scratches below the sound hole caused by strumming. Because of this you will receive a huge discount on this one of a kind Cornerstone Ukulele that would normally sell for over $5000.*

The solid top is made of Sinker Redwood (over 100 years underwater), master grade Curly Honduras Mahogany back and sides (that's correct 'curly' ... check out the photos).

Check out these custom features:

  • Blue Paua Abolone soundhole, purfing, fretboard, and headstock.
  • Koa wood "leaf" fretboard inlay at the 3rd, 5th, 7th, 10th, 12th, and 16th frets.
  • Ebony armrest that not only looks amazing but makes this ukulele comfortable to play weather your sitting or standing.

The sound? Just listen to the video to get some idea of the rich, bold projection with the crisp, fresh tones of the individual notes and the fabulous intonation up and down the neck. Remember, the speakers on our computers may not even do justice to the sound. Believe me, you will be honored and proud to own this treasure.

You might be asking yourself, "Why is a custom ukulele with so many features available for this incredibly reasonable price"? Great question and the answer is that this is a prototype of future custom ukuleles to come from Cornerstone. You get a one of the kind instrument with a lifetime warranty at an unheard of price for a customer ukulele. Hurry, I only have one and when it is snatched up ... well ...

CUSTOM SETUP - Each Cornerstone comes with a factory setup BUT I strongly recommend adding a setup especially if you want the easiest playability, have arthritis, or are particular about your setups and want a low action (how close the strings are to the fretboard) please click the "ADD Custom Setup" on this page.

* REQUIRED FOR WARRANTY - I cannot stress how important a humidifier is and I HIGHLY encourage you to get one. No matter where you live humidifiers not only protect your investment but also help the warranty process go smoother because you have taken the steps to ensure the safety and protection of your ukulele. If you ever have to contact Cornerstone he first question they will ask if you have a humidifier.

* Either the Oasis OH-18 (OH-32 for extra dry areas) or the Boveda Humidifier are recommended and available here at Click "ADD Humidifier"

*A PICKUP (several brands available) - click ADD Pickup . Normal install times are 2-3 weeks. If you want your instrument sooner please use the RUSH pickup option.

NOTE - This is a one of a kind, custom ukulele. You will receive the exact ukulele that is in the video and photos.
