1 macphisto 5 years ago now that we're seeing several Electromatics in the lineup with the "blacktop" Filters a la the Tim Armstrong guitar, the question naturally arises to me: how similar/different do these sound to the "regular" i.e. "High Sensitive" FilterTrons that are standard on pro-line Gretsches? this interests me since the new 544x Electros have blacktops and as such are a big step closer to FilterTron Jets than the previous ProJets. does anyone have experience with these pickups? Tim Armstrong owners? folks who've played the 544x prototypes that were given away at the Roundup in, where was it, Baltimore? (forgive my memory, it's 3:45 AM). anybody? Bueller?
