Karlwoodward @ www.rs-online.com/designspark is in the process of designing a “guitar pedal” for amplification and distortion using the Korg Nutube we featured earlier. The Part 1 of a series of articles goes through the basic aspects of tubes and valves, the pros and cons on using a Nutube valve as well as discussing about low gain and high source impedance. In Part 2 of the series he goes deeper by building a working prototype and making some measurements.
