Re: Modular preamp with dimebucker or JB
The preamp generally works best with much lower output pickups. Even the Gus G. Fire Blackouts set uses two very low output pickups boosted through the BMP-1 preamp.
Player feedback with higher output models has been generally unfavorable. Although, you might dig it, who knows...
If you've already got the BMP-1 and a JB or Dimebucker, I say give it a try. If not, consider the Dave Mustaine LiveWire set for a really great "active" JB or the AHB-3 "EMTY" Blackouts for something closer to the Dimebucker.
