Re: Custom 5 vs 59/Hybrid for All Types of Music ?
The Custom isn't a universal choice for 'all kinds of music', but then again, no pickup really is. There's always better choices that are specialized for certain genres. C5's are bright and midscooped, which works in some guitars for some genres. To me it's best in mahogany and similar woods that fill in the mids and add warmth. Whereas a Custom 2 (SH-11) may be too warm in an LP, it could be well-balanced in a Strat.
Hybrids humbuckers undo some the 'humbucker effect.' Humbuckers increase noise, high end, and clarity, while adding output and mids; the hotter the coils are wound, the more HB effect. Hybrid picks have an unmatched component, due to the difference in resistance, windings, etc between the coils, so they only have a partial humbucker effect. Some single coil tone is still present, making hybrids somewhat brighter, clearer, and less middy than matched coils. For that reason, I like hybrid HB's in the neck slot to clean up any hint of a dark, muddy pickup.
With a bridge hybrid, you're adding high-end and thinning out mids in a slot that is inherently brighter and thinner due to reduced string energy. That works in some applications for some players, but not for everybody. The '59/Custom has a huge coil mismatch, 7K vs 4.1K, so it's a bright pickup without a lot of mids,and you're hearing almost half of the individual coil of the Custom leaking thru (and a 7K PU is bright). Plus it has an A5, which is also bright and scooped. For me, the only way a bridge hybrid works is with a warm magnet like an A2, UOA5, or A8 to add back some of the warmth and mids to balance it's EQ.
The '59/Custom isn't a universal PU either, but maybe more so than a C5, but you've got some high-end to tame. To me, a straight '59B would work well for a number of genres. Have you considered that?
