Dan Armstrong Green Ringer Guitar Effect



The transistor marked ” * ” has no markings other than three stripes: green, blue and white from top to bottom. It is probably a log gain NPN used as a dual diode with the anodes connected together at the base of the final transistor.

The continuity test on the device shows no conductivity except that the topmost pin conducts when it is positive of the pins in the middle and other side; otherwise, no conduction. This  is I would expect if it were an NPN with the same pinout (base, collector, emittor) as the other transistors.
