The Jumbo was Gibson’s first ‘Dreadnought’ 14 fret flat top model. It was introduced in 1934, sold poorly, and was replaced by the J-35 in 1936; with a small number of transitional variants in between. With an incredibly clean 1935 Gibson Jumbo and a 1938 Gibson J-35 on hand, Mark discusses the Jumbo model in detail and compares it to the later J-35. Enjoy!
