Having done my research, the Gretsch G9201Honey Dipper Resonator certainly appeared my best option, and I am not disappointed.
Looking at the competition, price point, reviews across the internet and talking to friends who have their own opinions about such things, I took the gamble (despite my concerns about purchasing unseen, online and relying on postal delivery), delivery was efficient and the packaging ensured a safe delivery. I now am the proud owner of the exact same Gretsch Honey Dipper Resonator as played by Justin Johnson, I just need to get practicing, and possibly invest in an appropriate pick up system. In conclusion, I can’t find a fault, on opening the packaging found the set up from factory was spot on, strings are good (appear to be D’Addario EJ16 Phosphor Bronze, light .012 - .053 and just required tuning - to open G). All in all, very impressed both with guitar and Thomann level of service!
