I have a Spector Euro 5 that, as far as feel and playibility goes, I love. The tone just isn't quite right though. It has an EMG 2 band preamp and what I assume are EMG 40DC pickups. I feel like they just bring out the wrong frequencies, the treble seems strident and the mid-range inarticulate. Not sure what might be the best bet in terms of replacement, what will make the biggest difference? Preamp or Pickups? I also haven't played a lot of other basses so I don't have a lot of experience with other pickups. A set of custom spaced Nordstrand Big Singles seem like a good possibility from what I have read but I haven't been able to find a Youtube vid of anyone with those installed in a Spector. Throw any advice you have my way. I know this is kind of a rambling post.
