I am new to the forums and I hope this question is not out of order or in the wrong place.
I am reading and preparing to build my own guitar. My father did it back in the late 50's / 60's with the help of someone locally (SE Kansas). How they did it without the help of model luthier suppliers / tools, I don't know. He is passed now and I never asked. So, this is something that "I just have to do in life"!
I am fortunate to have a 1949 Gibson SJ, another one of his guitars that I absolutely love. My question is what other slope shouldered Jumbo's did Gibson make from this era? Was the J45 the same dimensions as the SJ?
I play a lot of Bluegrass and the SJ is perfect for this. I have hopes of building one similar one day.
