Been using a Hipshot A brass bridge for a few months, but I had to bag it because it adds noticeable weight to my 09 AmStd Precision and started getting to my bum shoulder. Not entirely happy about dumping it...I really like how adjustable it is, and how you don't have to thread the strings through a hole to load them. I also briefly met the owner of Hipshot at a gig recently, and he was a nice guy who seemed genuinely pleased I was happy with his bridge. But it bums me out even more to go home with a headache and a sore left shoulder and forearm, so it had to go. I replaced it with a Fender bent-plate bridge that used to come standard on MIA's until 2008 when they switched over to the higher mass bridge that came on my 2009. I don't care what anyone says...those bent plate bridges are fine bridges. The only thing wrong with them is you can't top load without threading the string through the hole. I will miss that, but I'll get over it. But man, do I hate what comes now...fine tuning the action and pickup height. Fine tuning string height isn't so bad. I'm almost there. But it bugs me to no end when a pickup is even a little off kilter with string volume. The next two weeks of gigs will go like this...play a couple songs, turn my back while someone talks and try to get it adjusted before the next song starts, play 4 more songs then lather, rinse, repeat for two weeks. So this bridge is now on there permanently and it'll take an act of God to make me change anything else after this. Thought about putting the stocker back on, but I've never been big on high mass bridges, even the "not really high mass" high mass Fender bridges, and opted to go with as little weight as possible. But while the Hipshot doesn't weigh much more than the stocker, and my shoulder problems never got worse using the stocker, I was surprised that even that slight little weight gain ended up taking its toll on my shoulder as much as it did. First month was fine, second month I started feeling a little extra pull, and now I seriously feel it, and even switching to the wider strap didn't fix it. I got the Hipshot to "cure" what I thought was a defect in the stock Fender bridge that ultimately turned out to be I got a couple sets of strings with D strings that falsely intonated. It's a very long story that I've already chronicled in another thread, and it ends with me looking like a yutz, so no need to rehash it But that problem is over with, and this is a much more important problem. Now I will thank you all in advance for all the different bridge suggestions I'm certain to get now, but the deed is done and I'm not going to replace this bent metal bridge unless it breaks in the future. I just mainly wanted to talk about how just a little bit of weight gain made all the difference as to whether I could continue using this bass. The Hipshot does feel heavier than the stocker but I wouldn't think it would develop into a problem for me because it can't be all that much difference. I don't have a postal scale but it can't be more than 4 or 5 ounces, no? Anyone know what they weigh exactly? Also, I wanted to vent about how much it sucks to replace a bass part you really like except for one fatal flaw, and I really wanted to vent about how irritating it is to finally get a bass nicely settled in then have to change a bridge and do a complete new setup and obsess on how it's not perfect for two weeks. I think my shrink and I will have a lot to talk about next visit (j/k...I don't see a shrink...I should, but I don't!).
