Hi all. I will immediately confess I am very ignorant of pick ups and preamps. I recently got a bass in trade that has a glockenlang pre with ken Armstrong pick ups. Bass sounds good I suppose but isn't really nailing the modern tone (more slap tone- lots of highs and lows with miss turned down). I really enjoy this bass and would hate to get rid of it so I am considering having pick ups and pre changed if it will help the bass get the tone I'm looking for. Any idea if this would help and pickup/preamp suggestion a would be greatly appreciated!!
