DiMarzio DP755BK

"The Tone Zone® 7 DP755BK. The Tone Zone® 7 is not merely an adaptation of the original Tone Zone®, but a new design from the ground up for 7-string guitars. It 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. The Tone Zone® 7 comes with 4-conductor cable. Recommended For Bridge position. Tech Talk We wanted to retain the power and sound of The Tone Zone® in The Tone Zone® 7, but we also wanted to reduce the magnet-pull to let the low “B” string resonate better. We 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 us to alter the construction of The Tone 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.
