Inside the 35TW pickup are both single and dual-coil pickups, each with its own output. The single-coil mode is a new version of our J pickup built in the CS (ceramic and steel). The dual-coil mode is our popular CS dual-coil consisting of two coils opposite one another creating a pickup similar to model 35CS. A push/pull volume (or tone) pot allows you to change from the clarity of a single-coil to the fatness of a dual-coil. The 35TW can be used with any of EMG's tone enhancing circuits on either pickup output. This pickup uses a 35 Extended housing that is 3.5 inches (89mm).
