I appreciate GC because it has the best stock of stuff in my area, and it's also one of the places you can find used gear. We have a good local store (Spotlight Music), but their business has shifted 75% online, and they don't stock much in the building any more. Unless I am shopping for new stuff, they're not a great deal of help to me and there's not much point in walking in the door. I'm mainly a used buyer, so that's not much appeal for me.
I'm glad GC went Chap 11 and will be able to continue in business. I haven't followed them financially but I hope they make it.
