A Joe Gagan classic. This version features the addition of a rotary switch as the Rangemaster section input cap selector. We've added four different caps, covering the original Rangemaster value, as well as three lower frequency values. Lots of texture available when you throw it into Ripper mode. If you don't want to fuss with germanium transistors, I've found that this circuit will also work very well with certain low gain silicon transistors, such as 2N2904A or 2N2905A.
