Re: SH-4 SH-5
Hmm interesting. I have an Epihpone Les Paul standard, with the type of wood used do you think the outcome wouldn't be so great?
That's just it, it's hard to tell in advance. JB's were made for bright woods (where they are reliable), and are hit or miss in warm woods like mahogany. They can do very well in mahogany or they can get an annoying 'ice pick spike' and a pretty loose low end. You won't know until you put one in your guitar. And those downsides can be accentuated even more in a fat-bodied LP. It's a roll of the dice.
If you're playing metal and hard rock, a Custom (SH-5) is a much better bet. If you're playing hard rock, classic rock, and blues (like I do), a C8 is great (SH-5 with an A8 magnet). The C8 is
very popular here. Warm, powerful, full mids, tight low end, high output. Great clean or distorted.
BTW, bridge PU's are overwound to make them warmer and louder, because the bridge slot is naturally bright, sharp, and weak. But the neck position is naturally warm and loud, so putting a hot bridge PU there often means that you get a dark, muffled tone, maybe muddy, that can drown out the bridge PU.
