Thank you. It's actually solid Koa. The E series was known as the Little Jumbo. It's shaped like a Tacoma Jumbo guitar, but is in fact smaller than a Dread. The first letter in the model is the series (P for Papoose or Parlor, J for Jumbo, D for Dread, E for Little Jumbo, C for Chief, R for Roadking) with the next two letters telling you what the top and body are. Most of the Tacomas were topped with Spruce, and that was assumed, leaving DR for Rosewood bodied Dread, or JM for Mahogany bodied Jumbo. Two letters meant a different top. Mine is a EKK for Koa body and top. Finally, the numbers indicated level of trim. The higher the number, the fancier guitar. 40 indicates a very dressy axe, while 55 was about the top. 9 was a very simple model, etc. and, other than ornateness, I can't tell any difference in the quality of the wood between levels. So mine is a Little Jumbo with Koa top and sides, at level 9 trim - little jumbo, satin finish, Koa front, back and sides, mahogany neck, rosewood fingerboard, tortoise shell binding on body and neck, herringbone inlays, 20 frets, full body.
My church's band is sponsored by Koa and all the Acoustic Players have Taylor Koa Guitars...also very beautiful in both looks and sound.
Those would have been awesome tours to see! Green Day is one of my favorite bands musically.
