I have both neck and bridge pickups. I also have a livewire metal.
If you ask my opinion, I will not use classic neck and metal bridge because they are totally mismatch in terms of output level. Think SSL1 in neck and Invader in bridge X 1000. I'd rather use LW metal in a single humbucker guitar.
The HC review also somehow confirms my view on them.

BTW, I currently have over 50 pickups in my house and I have been installing pickups by myself for over 15 years. I have owned many amps (Marshalls, Rivera, Soldano, etc etc) and I currently own three tube amps (Mesa Mark IV, Fender Bassman RI, Traynor). I have 10+ guitars (Gibson Les Paul, Flying V, Fender Strats, teles, 335 copy, Brian Moore, etc etc). I have installed EMGs and Livewires and they all worked just fine. So it's not the case that I installed the pickups incorrectly or I installed them in a cheap guitar and played through a cheap SS amp, **** it!
The question is why LW classic was voiced bright and thin, and why SD marketed that LW classic neck is a good match for LW metal. I just want to know the reason behind those decisions.
