Its a good quality brass but not so much sustain.

Great quality. Does what it supposed to do.

Sound does appear to be more massive (unplugged).

I have Floyd Rose equipped guitar and a PRS Tremonti. Both guitars have similar output pickups, yet the former was quite shrill and the actual output was noticably less, so I bought this upgrade, hoping to solve the problem. This hunk of brass will noticably round off the highs and bring out the mids/lower mids. I use a Marshall JCM 800, which is quite a trebly amp and I noticed an output increase as well, so I don't have to have the gain as high. It won't make a Floyd equipped guitar sound like a Les Paul, but the tonal upgrade is easily one of the best £30 I've ever spent.

There's not much to say here. It's exactly what it claims to be. It's a big honkin' chonker of a sustain block. Gave my Strandberg a more rounded, less trebly tone when unplugged than the aluminum block it had before. Sustained exactly the same, but made the trem feel a lot better in use, with smoother action and a faster return to zero. I ended up returning it because it poked out of the bottom of the cavity a bit, but that's not the fault of the product in any way; it just goes to show that you shouldn't believe everything you read on Reddit. Easy 5-star block, just don't put it in a Strandberg if you care about your block being recessed.
