Hey people, I'm pretty new to the guitar parts and all and here too (so nice meeting you all), but I was just wondering about something. I ordered a wilkinson tremolo kit for my fender as a replacement and says what I ordered, it has stainless steel saddles and a solid steel block. But the thing is, if its a solid steel block, wouldn't a magnet stick to the block? (because it doesnt at all) and if its stainless steel saddles wouldn't the magnet not stick that much to them? (because it does like iron/steel). The block does seem pretty heavy and appear to look like steel in a way, but is there anyway to really tell or insight?. Im thinking it could be zinc or some other mixtures.Thanks.
