[br]I have never owned a guitar with a bigsby, but I've heard and read a lot about them. They seem to have a reputation for making your tuning very unstable.
[br]Personally, I'm not a big user of whammy/tremelo systems. However, I was lucky enough to try a Joe Walsh signature Duesenberg recently and they have a similar tremelo system to the bigsby, but it was very stable - tuning wise. And apparently, very easy to change strings, acording to the owner - he wasn't trying to sell it to me either. He loves it and he has over 30yrs experience with guitars. I tried to make an offer but he wasn't letting go of it. haha! It really was a beautifully crafted instrument. Could be worth checking them out.
[br]Would love to hear what you go for in the end Dale. Good luck.
