Still diggin' the Stets. My #1 is a nice little Ebony, but still has no Bigsby. No need. Not for the style of music I play. The only thing I need a little "whammy" for is a couple of VH tunes, but I've got the Strat copy for that.
At any rate, if I were to put a vibrato system on an LP, the guitar would pick its own system.
For example, a BB3 would have to have a gold B7, whereas a nice plaintop or plustop would get the Stets (IMO...).
That's just me and the way I think. I've seen several members here with all different types of LPs with Bigsbys that look great. Just not for me.
