I want to have a change in sound on my 4 String Warwick corvette Standard. Currently the bass using a set of EMG Jazz Set and a 2 Band Bartolini Preamp. The bass string with DR Fatbeam 40-100. The sound is agressive but it lean towards the trebly sight. I think this is because the EMG pickups are trebly. I'm looking for something that give more low mid and fat but keeps the agressive modern sound. Any pickup recommended? I was thinking about putting 2 humbucker to replace the 2 EMG Jazz, but then i will encounter length problem on the bridge pickup. Unless i keep the jazz on the bridge but replace the neck pickup with humbucker. Also I'm interest on the big pole piece pickups for more beef on the sound.
