Ovation’s Applause ukuleles are probably the most popular electric ukes around. Ukulele4u are currently selling the new Applause Tenor ukulele. Personally, I much prefer the natural wood look of these ukes to the black finish of other models.
On the Martin front, there’s a Martin 2K and a Martin Tiple.
The most unusual uke up for grabs this week is the Harp Ukulele. As well as the four standard ukulele strings, it has four bass strings (intended to be tuned to an open chord). You can read more about this and other harp ukuleles here, see the photos of the first family of harp instruments the Knutsens, and watch Andy McKee pwning the harp guitar (as I believe the kids are saying nowadays).
