Okay, basically you won't find this anywhere on the net, tried it already, but here's how to get some voltage gain from an emitter follower. Typically the common collector amplifier has 100% emitter degeneration, which restricts the maximum voltage gain to 1. Once you add the internal resistance of the transistor the voltage gain goes a little below 1. The only thing that restricts the voltage gain is the 100% negative feedback employed by the emitter resistor. If we can somehow take some of the negative feedback off, the voltage gain will increase. Basically this is the way, you tap the load at some point and take an output to feed back to the input. This is basically sort of a bootstrap (not exactly). The voltage gain is then completely independent from the transistor hFe. The gain can be approximated this way. The lower part of the potentiometer divided by the upper one, summed with 1. Av=(3.3/1)+1=4.3 times. Due to loading from the feedback and the load itself and the internal resistance of the transistor, the gain is slightly less, but the formula gives a good estimate. You can try different wiper positions to see how the gain varies.
