I'm going to be putting a non-locking whammy on my upcoming Warmoth 7-string. I want it for warbles and shimmers a la Jeff Beck, not divebombing or squealing. With that many strings, I figure to use at least four springs. It's been a few decades since I dealt with anything wobblier than a Bigsby (creak, creak, drool shuffle) , and they have all these new-fangled "improvement" nowadays. The Trem-Setter appears to be a hydraulic shock-absorber? Would there be any advantage, with four springs & seven strings?
