just wondering if anyone has ever used one, and if it really helped, noticeably, thanks!
It's simple physics, add more weight, increase the sustain.
I don't think it will make a world of difference as it would on a standard trem like on a strat. The strings are cut off and stopped at the top of the bridge and don't go down through the bottom where the sustain block is.
^While I agree somewhat I think physics still prevails.
Yes, alot of people recommend them too.
