I play a Fender Nate Mendell P Bass. I love the punch that my A and D strings have. I wish I were as enthused about what my E and G strings sound like. But my main concern is that when I play the 12 fret on the D string when playing with the band I can barely hear the note. Would this be a possible dead spot and would a compressor help me? I've never used one and I don't want to spent much to try one. Should I buy an inexpensive one like a Behringer for $25 to see if it helps? Any opinions would help. I'm brand new here. Thanks!
