DiMarzio DP755 Tone Zone 7 Seven String Guitar Pickup Humbucker
Almost as soon as they introduced 7-string pickups, DiMarzio began receiving requests for a 7-string version of the Tone Zone. Here it is. The Tone Zone 7 is not simply a 7-string copy of the original Tone Zone, but rather a new design that incorporates lower magnet-pull and coils specifically calibrated to reproduce the full impact of the low B string without any loss of tone quality or fidelity.
Recommended For: Bridge position
DiMarzio wanted to retain the power and sound of the Tone Zone® in the Tone Zone 7TM, but they also wanted to reduce the magnet-pull to let the low B string resonate better. They found the best way to do this was to use a ceramic magnet, rather than the Alnico 5 magnet employed in the original Tone Zone®. The physical differences between 7 and 6-string pickups allowed them to alter the construction of the 'Zone 7 so that it performs as if it has an Alnico magnet, but its ceramic magnet is actually more stable over time, and there's about 40% less magnet pull.
