That is the difference lol. Tie block bridge as well, a wider neck without radius, slotted headstock, 5mm upcurve on the neck, and of course, Nylon Strings. @@StarStew
I remember seeing the preview for this on a VHS tape as a kid, when I finally rented it from blockbuster in my late teens, I was into it, and part of that came from the soundtrack. Your performance is legit man, an awesome tribute to a classic.
I hate to knock someone's RU-vid hustle but this is a mess. Pitch problems galore and the arrangement is just a bunch of ukes clashing against each other. Maybe take some time away from this and listen again. I think you'll probably hear it.
