You can just use the tuners like a normal hard tail definitely.
To be honest sometimes i do just that with my 77FP as the tuning stability of the Lo Pro is so good that it stays in tune without locking it down anyway.
I have just installed a tremolo-no on my friend's JS100 and it works fine.
Just one problem that we noticed when installing it. wonder if anyone else has seen this...
The
trem claw on pretty much all
Ibanez guitars is quite thin (about 2 mm). The trem claw fixed to the tremelo- no is more like 5 or 6mm. This means that when you switch claws and screw it back in the screws that go into the body of the guitar have to be screwed in about half a cm less.
When we first installed the T-no the original screws were not long enough and when not fully screwed in the tension from the springs ripped them out of the guitar. Had to go get some new longer screws and now it works fine. but it seems like a bit of a design flaw.
(hope everyone understood that without a diagram!)
