Bassist in my band is looking to pimp out his bass a bit. He's got an LTD D6. What do you guys think would be more beneficial, swapping out the preamp or swapping out the pickups? I know this is a bit of a broad question, but bear with me.
He's looking specifically for EMG's. What do you guys recommend?
Unless your preamp is terrible, it should be fairly transparent. Try this: Listen to the bridge pickup then disconnect it from the preamp and connect it direct to the output jack. Is the difference significant and life altering? If not, change pickups.
If he's putting in EMGs, I think the preamps on those are internal to the pickups themselves. They have EQ and other accessories you can get, but i dont know too much about that.
