DiMarzio DP291 New’Tron Neck Pickup (Nickel Cover With Cream Insert)The classic FilterTron sound resides somewhere between a Gibson ES 335 and a Fender Telecaster on the guitar tone spectrum. These hum canceling pickups were designed by Ray Butts in the mid 50s, with input and direction from Chet Atkins for the Gretsch company. At that time, Atkins was working on an improved version of his signature guitar and voiced concerns about the noise produced by the single coil pickups in the earlier iterations of his guitars.
