If you don't get a trem then how are you going to "flatten" notes???
If you ONLY bend "up" (with your fingers/trem), aren't you missing the whole other half of guitar notes???
And, since you can't bend to flatten notes with your fingers, the only way you can flatten a note (i.e., bend down) is by using a trem.
A trem is not just for dive bombs, it's to bend down every single possible note, the same amount that you bend up with your fingers!!
Damn right saying, TNT! Another reason to acquire a trem...
