I'm glad to help. Everyone has helped me so much on UU that i was happy to give advise/opinion for a change instead of taking. Don't get me wrong. I love my Lu21 but it is a laminated product. If you are already lucky enough to be playing a solid mahogany Concert, a move to a laminated may be a little disapointing with regards to sound quality. Like I said, I like the sound on my a lot but I have recntly had the opertunity to test ride a solid uku and you can hear the difference, even with my ears! If you remember, let me know what you end up doing?
