I am a long time lurker but have something to share. I was changing the 40 year old springs in my 1975 Mustang's tremolo and wondered why I haven't seen anyone block the tremolo so it only works to loosen the strings and then it will always return to tune when you let the tremolo go? It won't be a floating tremolo but it would make the guitar way more useful. I have done this with all my Strats for over 30 years by screwing the claw all the way down.
This is the victim. A 1975 Fender Mustang I rescued on a business trip to Des Moines over 15 years ago.
