i did a live show DVD recording gig sometime ago.
I was using my UV77PW and a "Custom RED 7 string" for backup.
I was switching the babies during the songs since they sound diferent a little.
Then suddenly one string fell out off the UV. Not broke, just fell out from the Lo Pro Edge bridge.
It was the last note of that 4th song. Not affected the recording at all.
I don't even moved from stage: i just got the tool, opened the saddle, re-put the string on.
Just unlocked the pressure pad to check the tunning, retuned the string (D) and locked the nut.
Did the fine tunning.
All of this took something like 20 to 30 secounds...
I was incredbly fast!!! and CALM!
So the recording continued without issues.
For the OP: always on original cases.
Actually, when you arrive to the gig with such a nice cool looking cases like Ibanez Prestige ones, you look so pro!
But never, never leave them alone or someone will steal it!
Same with your trem arm. I do take special care of them, since they are hugely overpriced (AND RARE!) here in the 3rd world!
We dont get spare parts from Ibz distributor... go figure.
