Well I'm digging into whammy bar usage like never before.
Tuning is holding up quite well and I'm seriously considering getting a 'Tele' version...
5 days in then TWANG!!
E six and D four stings suddenly let go.
Investigating the result
Both broke where they bend around the main shaft by the looks.
I remember noticing some increased 'creaks' from this area over the past day.
I'm also using an el-cheapo "Darco" brand strings from JB-HiFi.
The action has risen somewhat and the saddles are in their lowest setting down on the body.
So I've put a shim in the neck and replaced the 2 strings.
I'll now give it another work-out and see if the issue recurs.
May have to try better quality strings...
Then if the problem persists perhaps some strengthening solder to that area of new strings.
