If you like the tone of the stock Dimarzios, then you may get more mileage for less money by putting in an active boost module. Either from EMG or Bartolini. If you didn't want to add a switch to turn it on, you could forego the hi-pass filter on the volume knob in favor of the boost. You also could just get Seymour Duncan's line driver pedal. I think its called a pickup driver or booster. Whatever it's called it might do the trick for you. MXR made some kind of line booster, too. Then you'd have the best of both worlds, but you'd also know if the output is your only problem, or if you also want more mids/highs etc. Then you'd have a better idea which pickups to get.
