I remember talking to Matt around the time they were making the change a few months ago and he said it was difficult to use the complex logo in social media and marketing, and that the simpler logo made it a lot easier.
Personally, I find the new stuff a bit cartoonish and really thought the old one was very classy looking, even though the new one harkens back to the even older Curtis heritage. The SRT is on my short list for my next solo and I’m hoping they would still be able to do the old Hemlock logo. Just my personal preference.
