How much does an electric guitar processor cost?

Answer 1

If by processor, you mean single or humbucker pickups, they can vary from as little as $20 to several hundred per coil. It all depends on your playing style and the annotation configuration of the sound you are looking for. It will also vary on the factory brand (Dimarzzio, Seynour Duncan, etc.) or some cheaply made knock-offs. Don't let the visuals fool you. Even the ugliest pickup can sound awesome.
