I am proud of you too.
I attribute good learning abilities to periodic shocking events, but whatever floats your boat as long as you survive and learn.

Now about the volume: it is possible that the low volume is attributable to the fact that magnetic is low impedance and piezo is high so without proper input impedance adjusting (transformer or input circuit mod) it might stay low. But..may be OK if you don't mind.
