Ill start, Flock Of Seagull’s Paul Reynolds. I would consider his general sound to be the most refined 80’s reverbed overdriven guitar tone there is. It’s a bit harder for synth tones but I’d say M83 is fairly underrated for his synth tones even though he has lots of praise for his music.
One underrated guitar tone that I can think of is Billy Duffy’s especially in The Cult’s Sonic Temple. Ooh boy that tone is sexy. Also Robert Quines’ tone in Girlfriend, damn damn damn I need a napkin.
