1 Golem 4 months ago I can't imagine a better place to ask about Bigby vibratos than a Gretsch forum, even if the guitar in question is a PRS.I picked up a PRS Starla S2 in trade for an amp plus cash on my end. I can't complain about the deal I got. It sounds great and I love the neck and locking tuners. But I do notice that this Bigsby is stiffer than other Starlas I've tried and the only other Bigsby equipped guitar I've ever owned. My first thought is to try different springs but I don't know which ones to buy and where to get them. I also read about people putting a coin under spring of some Bigsby vibrators. It's so easily reversible that I can't imagine not at least giving it a try. But which coin?I also read about people loosening a nut, but people were arguing about whether that was actually a good idea or not. I couldn't figure out what nut they meant and it wasn't an experiment I wanted to try.Anyhow, I'm hoping y'all don't mind me joining this forum. I may not own a Gretsch, but I'm a big fan of various flavors and interpretations of Filtertrons, DynaSonics, and Hilotrons.
