During a time when cultural optimism was low, Gibson dreamed up a new line of "advanced" instruments; included in those models was the Advanced Jumbo. Due to low production numbers from 1936–1939, this model largely flew under the radar even though it was a supreme sounding and performing instrument. The Gibson Acoustic Custom Shop 1936 Advanced Jumbo is outfitted with a Thermally Aged Adirondack red spruce top, mahogany back and sides and premium Waverly tuners. The 1936 Gibson Advanced Jumbo brings back all the tone and prestige that made these sought-after instruments by artists and collectors.
