Take a Super Distortion®, include a push-pull pot for series-parallel or single-coil operation and you have the Dual Sound®. The extra flexibility puts cleaner, crisp tone choices at your control. Lighten up on the lead tone in parallel operation, then roar back in with the standard series position. 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.
The Dual Sound® is the original 4-conductor version of the Super Distortion®. Originally, the main purpose of 4-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 True 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.
