Umm... awesome! Why should Junior Brown have all the fun with crazy double-necked instruments. Should I have to suffer the injustice of a single neck ukulele just because they don't exist. Nope. They do exist! Check out this Double Neck Ukulele.
This is definitely a first for me. Although now that I've had a taste, I want more more more! Give me a dual-neck ukulele/tiple combo! That would rule. Although, I should probably get proficient at a single-neck uke before I go getting greedy.
