For practice I just finished breadboarding the confidence boost kit and it's working but the gain is very high. The pot at 50% is no where near unity. I ran through the trouble shooting steps and everything checked out except for "The emitter of the transistor (E pad) should have about 1 volt or so. (my build has 0.98 volts)". I'm reading only 0.15v on the emitter. Not sure if that's related. Anyway, it works and it was fun but I wanted to check if there was something simple I screwed up that would lead to the low voltage on the emitter and the extra gain. If I take the signal from right after the buffer it's perfect.
