I recently learned the ukulele and love it for its easiness, size, and novelty. Do you think a uke would work well with electric guitars, in a pop punk band? One of the only bands I can think of that uses a different instrument is Yellowcard, with a violin, and they incorporate it pretty well. Having "exotic" or uncommon instruments tends to add a uniqueness to your band and elicit more of a respponse form the crowd. For example, the band Flatfoot 56 has bagpipes, and, due to their uniqueness, they tend to be the staple of the band. What do you think about working instruments into genres about which they are not generally found, like my example of a ukulele in a pop punk band, or any other example? Is it to gimmicky? Could it draw people away? Or will it be beneficial and set you apart?
