Not clickbait.

In this video I actually did bang a bulging tranny with a rock hard object. I'm not ashamed. I will NOT apologize. Some other things also happen in the video, such as troubleshooting the tremolo on a Fender amp, replacing 6V6 tubes that some rube stupidly installed without so much as rebiasing. We'll also dress the amp up in blackface, which is probably the least controversial thing we do in the video. On another note, I can't figure out why the algorithm hates me so much. Maybe one day it will become clear to me.
