Upgraded the tuner buttons on my J-45 Standard! in Gibson Acoustic Posted October 7, 2019 · Report reply On 10/4/2019 at 3:22 PM, ALD323 said: Olie thanks for the updates...I just ordered 2 sets of these these as well, and can't wait to make my 2013 J-45 look better...as well as my new J-45 Studio model. These buttons will go on both. Like you, I like the way, they work perfect and found no reason to replace them...these Ivoroid acrylic buttons are beautiful too. Those who want these might consider ordering them as 44 sets of these have been sold already. These buttons look great, and the company in Taiwan who makes them are very honest and easy to work with, having responded with them repeatedly. I have requested them to attempt to produce Gibson Hummingbird Jade Tulip buttons for the gibson hummingbird rotomatics. You might want to drop a bug in their ear by email about the Jade Tulip buttons exclusively made for rotomatics..we could just end up with the perfect solution for those steely looking heavy rotomatics on a hummingbird. I told them I would order those Tulip buttons in a heartbeat should they decide to produce them...and so likely would many others who are stuck with those cold clunky rotomatic tuners Gibson insists on using on the hummingbird standard model. ..Many thanks to the original poster of this thread JJrpilot. Sooo glad you posted this! And thanks Olie for your update on these J-45 acrylic Ivoroid button replacements for the J-45. These buttons are a brilliant way to have your cake and eat it too! No problem at all! Hope you get yours soon! The savings in weight alone is worth it not to mention we don't have to drill new holes etc.
