I recently picked up two new basses in the past year. Both are Sterling by Musicman stingray basses. One is a 5 string with one pickup. The other is a 4 string with two pickups. The 5 string sounds as I think it is supposed to, but some strange reason the 4 string HH has this nasty midrange that you can't even get rid of with EQ. At first I thought it was because it had cheap pickups in it, but the site says it uses the same type they put in US made stringrays. Maybe its the wiring? I can't find any concrete information on how one is wired compared to the other. Any info on this you guys have will help me. Schematics, experiences, audio clips, etc. Both basses are currently strung with Ernie Ball regular slinky strings. I can make sound clips if needed.
