Honestly, as I've stated before, I absolutely don't understand the lure of a hardtail guitar AT ALL!, but that's for another thread.
I can't live without the tremolo on my guitar.
I've tried blocking it a few times, but I can never keep it that way for more than a few days. I have to have the tremolo!
One of the reasons I don't understand hardtail Strats is that the tremolo is a part of the tone.
I think I read somewhere that (Clapton?? Can't remember who.) blocks his trems, but leaves the springs in, because it's part of the Strat tone.
Another reason to have a trem, but not use it is so that you CAN use it when you need to, even if you usually don't.
Which is another reason why I don't get you hardtail players. Why not block the trem and silence the springs instead, that way you can have the tremolo if you need it, but don't have to have it all the time.
You're only a setup away from having, or not having a trem on the guitar.
