Part 1: Is there generally any kind of consensus on whether blocking a floating trem will damper sustain? I mean, people upgrade their blocks all the time to get better sustain... but that block is floating between the strings and the springs, can vibrate well enough to keep on sustaining. How is that affected by putting in blocks? I never took physics. Do you suspect that blocking a floating trem would increase or decrease sustain? Part 2: What do you suppose would be the "best" way to block a trem, with regards to tone (over stability)? -They offer a lot of things you can screw into your guitar body and adjust, like just a little tiny grub screw pushing against the block. -I've heard to use business cards or playing cards. Though I don't understand why I feel inclined to believe so, but I have to imagine that this would damper the guitars tone in some way. -I'm currently using popsicle sticks wrapped in masking tape right now. It is not satisfactory. Constantly needs retuning. Maybe it's the pressure squishing the popsicle sticks together. -I've heard to use coins. Now this seems like a good idea. The pressure can't really compress them, so it should be more stable. Also, coins are made of metal, so by the same logic that getting a big brass block is good for sustain... maybe blocking with metal coins is less detrimental to sustain than say, business cards? -What about wood blocks? Guitars are made of wood, after all. Part 3: Is it better to have the blocks make as much contact with the trem block as possible, or as little as possible? I mean, the products that are designed for this sort of thing are often little tiny grub screws that barely make any surface contact. But then again, those products sorta have to be small in order to be installed between the springs. But say I were to cut some custom wood blocks ore something, would I want to make them as large as possible, or as small as possible? I'm sorry this is so confusing since both the blocks and the block are called blocks.
