Glenn Nichols of Retrograde Guitars builds instruments inspired by the catalog guitars of the 1940s and '50s. For episode 63 of the podcast, he tells us how he is re-imagining laminated tops and how he treats them as acoustically tunable plates. He also shares how, after getting a degree in art, he ended up working for Santa Cruz guitars and luthiers Kenny Hill and Bill Tippin. We also talk about the spirit varnish he uses on all his guitars, his wood choices and more.  This episode is sponsored by Acoustic Coffee Company, Allied Lutherie and Dream Guitars.
