That set up will be a piece of cake dwasifar, she's a beautiful guitar for sure. So glad Guild made this right.
On the case issue, I'll tell you a little story. Bill Collings, as he was obsessed with guitar building, was also obsessed with guitar cases. So much so that Bill designed his own cases, with every aspect/part of the case manufactured in house by Collings.......even the case latches. Bill called it the Collings Traditional case. Collings built the Traditional case from around '17 till around late '19. As an accessory, they sold for $800-$1000, but were factory equipment with a new guitar for those 2-3 years. I've got an '18 D2HA and it came with the Traditional case, and I assure you they are the finest case I've ever owned.
Then when Bill died, they discontinued production of the Traditional cases. Man, the Collings world turned upside down. In the beginning I didn't fully understand what all the complaints were all about as I also have a Collings CJ that came with a TKL case, nothing spectacular, but functional. Then later I bought the D2 and discovered what all the excitement was regarding the Traditional cases.
Fast forward to my ordering my newest D1A, knowing it would come with a TKL case, which was fine......I was buying the guitar, not the case really. The D1A arrives, and after growing accustomed to the Traditional case of the D2, the TKL case was, and is a real letdown. Just like yours, the center strap that limits the opening of the case top is too short. They may not sound like a big deal, but if one isn't careful, that top AND those latches could potentially fall right on to the top of a guitar being put into or taken out of the case. The TKL case doesn't mesh well either, as I have to kind of jiggle the top to get the latches to mesh. I'd never appreciated a well thought out, well built guitar case until I grew accustomed to the Traditional case, THEN got the new TKL case. I have to be extremely careful with this new TKL case. I was taking a guitar out of the new TKL case one day, and did NOT have my other hand on the lid. I got the guitar half way out as the case lid began to drop. Fortunately i was able to quickly snatch the guitar out from under the lid before it fell. Otherwise there would have been latch claw marks all over the top of that guitar. It's made me a believer in fine guitar cases. I suppose what we both need to do is cut and extend that center strap.
My guess is that Collings was using so many resources on case building that when their back orders began growing due to Covid, something had to give, so they discontinued their case building.
The Traditional cases now sell for around $1400, IF you can find one. What I see quite a bit on Reverb are folks selling '17-'19 Collings guitars with TKL or other cases, and what those sellers do is sell their Traditional case separately for $1400, then buy a TKL case for $250, and sell the guitar with it.
Not sure who makes those cases for Guild, but I'll bet they are TKL?
On a different not, I was very sorry to hear about your family member. It sure puts the priority of guitars in perspective though. I hope all turns out well for you sir, both the family member and the D55.
