DiMarzio Blaze 7-String Bridge Pickup Black Blaze for 7 stringNeckThis is the model originally designed for the neck position of the Ibanez Universe The neck position needs to be warm, but not too fat (nobody wants the low "B" sounding like a tuba, right?), so DiMarzio scooped out some of the mids to brighten up the low notes and kept the power down to a reasonable level to avoid unnecessary sludge MiddleSeven-string guitars are hard to amplify Most players tune the seventh string to a low B (or even A), and it's a real trick to get a big, solid tone from the other strings without the seventh turning to mud The Blaze single-coil is exceptionally tight, and is designed to be a match for the Blaze humbuckers in split mode
