Dang, that's a surprise! And, I agree, good news for the guitar community!
I’ve owned two WM-45s, and as good as they were, I ran into other J-45ish models that ended up replacing them. Gibson has been incredibly prolific with their use of the J-45 platform, to the point that any conceivable tone you might be after is most likely out there - you just have to get lucky & find it!And I hope it means they are bringing the WM-45 back into production!
