Bought myself an original Floyd Rose after having my guitar’s old trem blocked (hard tailed) for the longest , my old trem just wouldn’t stay in tune ! But anyway after installing the Floyd I was happy to finally have a functioning trem but something about the tone felt off compared to how it was when it was blocked . The notes felt kind of lifeless , they’d fade away quickly and it just sounded dull like something was missing..I bought a 42mm block and now it is alive again ! I know there’s a lot of skeptics out there and there are some people who say this stuff is a waste of money but I’d argue that in some cases installing a big brass block is similar to installing new pickups . I highly recommend getting the biggest block you can fit for the most noticeable difference ! The thin brass blocks out there don’t make much of an audible difference , bigger is better in my opinion . It also helps darken a guitar if it is too bright , if your guitar is already dark sounding it will actually make it sound even darker .The tone now sounds richer , more sustain and less thin . If you’re skeptical give it a try , especially if you have a trem loaded guitar that sounds like it’s lacking something . It’s worth a try !
