Every time I change strings on my JTV-69, the entire tremolo assembly pops out, causing me to open up the back panel, re-insert the spring/s that has/have managed to work free, before continuing with the re-stringing. I think it is the tremolo spring design, but it could also be the design of 2-pin anchor for the trem assembly on the top of the guitar. Once the spring pops off, it takes a lot of manhandling to get the whole system in place again.I admit that I did install heat-shrink material on my springs (to control ghost notes through the sensors), but the heatshrink is not tight, and is not inhibiting the springs in any way.
I've owned lots of strats with similar trem setups, and never experienced this problem. Anyone else experienced this? Any fixes out there I can try?
Many thanks, Larry
