Ahhh, chapstick, of course! Durrrr, I should have realized. But I read "a little chopstick" and was picturing some teeny piece of wood or something...! Yeah, rocket scientist, that's me...
Thanks much for the trem info-- agreed, I've also read high praise of the EBMM trem system. Glad to know that tweaking is normal. Never having had one before, I won't be urgently needing it, just wanted to have one on one of my guitars.
Another feature of this guitar is a compensated nut, so I am reluctant to mess with it unless really necessary. I'll take your advice and watch the Youtubes and learn what I can. Worst case, I can always bring it to my FNGS and ask them to show me the ropes-- some really good techs there.
Thanks again Bob!
