Dual Sound Use the single-coil mode along with your neck or middle pickup for chopping rhythm tones. If you need brighter, more transparent sounds from your bridge or neck pickup without sacrificing wide, singing crunch, the Dual Sound nicely fills the bill. Recommended For: Bridge position on solid body guitars. Tech Talk: The Dual Sound is the original four-conductor version of the Super Distortion. Originally, the main purpose of four-conductor wiring was to switch from series to parallel modes. It is now popular in bridge position H-S-H pickup arrangements, where it can split to single-coil in combination with a middle position pickup like the Blue Velvet. This combination creates very Strat-like sounds, because the warm tone and high output of the Dual Sound allow single-coil mode to balance with most single-coils.. "Take a DiMarzio Super Distortion humbucker, add a mini-switch and 4-conductor wiring for parallel and single-coil operation, and you have the DiMarzio Dual Sound pickup! The extra flexibility puts cleaner, crisper tone choices at your control. Lighten up on the lead tone in parallel operation, then roar back in with the standard series position or use the single-coil mode along with the neck or middle pickup for chopping rhythm tones. If you crave brighter, more transparent sounds from your bridge or neck pickup without sacrificing wide, singing crunch, the Dual Sound fills the bill."
