The Signature set is Ron's own recipe in creating the ultimate Humbucker style pickup. The set is a result of finding single-coil clarity in the humbucker format. The Signature set produces slightly less mid-range content, and clearly articulates both high and low notes to create a clean and melodic tonal signature.
The Signature set uses a unique recipe of materials to deliver the best of the best clear and articulate Product Applied For (PAF) sound and feel. It's great for articulate playing and works well in combination with Telecaster, Stratocaster, and P90 pickups.
For clean and rich tonal response, the Signature set is the way to go.
