The great Chet Atkins had an excellent partnership with Gretsch, which yielded many signature pieces bearing his name. This amp is a simplistic but great sounding design, and even has the added bonus of harmonic tremolo! It sounds excellent all around, and is great for Chet style playing, as one might expect. The amp is mostly original, aside from a changed power cord, and one speaker swapped for a late 60's Oxford. The amp shows minor signs of wear, and still looks great overall.
