I am looking into picking up a Setzer Hot Rod, but not quite knowing the history of the differences over the years, and doing some research, I get the same amount of knowledge and confusion . Is there a particular era that is considered above and beyond the rest, or are there too many variances that play to personal taste? Are the pre-FMICs OK? Are there any particular years to shy away from? FWIW, I tend to prefer thicker and/or V-neck profiles, but I can adapt. I have a 5420T that I like the neck profile on, if that helps. I also am a fan of the two-tone 2015-2019 look.
