I just purchased a 2002 Heritage H-535 (like a Gibson ES-335) that has stock Schaller pickups in it. They sound a little too muddy, and too mid-rangy for my ear. I'd like something with tighter lows and a little less mid-range. If Larry Carlton had a few beers and relaxed into a blues jam - imagine that tone. What do you guys suggest for replacement pickups? I don't need to go all the way to Lollars, etc. I'm guessing that Duncan makes something?
