I agree with what Drew said. It's about balance... but when achieving that balance, you want the things that focus on the tonal ends you desire.
If you have a mid-heavy setup, the Blaze Bridge sounds
exactly like what you want. It is very clear, has great bass (but not boomy or woofy. Very tight), scooped mids (relative to 'hot' pickups. But to me, the mids are very pleasant, even, and balanced), and terrific treble (but not screechy or shrill).
If you have a setup that already is scooped, a la, a basswood body with a Dual Rectifier with mids at 0, bass and treble at 10, for example
, then the Blaze Custom would be a bit more to your liking. It sounds a
lot like the Blaze Bridge, but it has a bit of a bumped midrange (not high or low mids, either. The solid mid-midrange, for lack of better term) and increased output (although this is not appreciably noticable to the ear. Both are relatively hot, but the smooth gain and mild compression on many Dimarzios make them sound much more... balanced, I guess, as for as output/loudness is concerned).
