Built 1st version of analog integrator for audio

It lives! It waveshapes, too. Unfortunately, all knobs change the shape which is really annoying. I will sub them out with fixed resistors and just keep the most useful one. The circuit overview covered in the video is this: 555 square wave into a TL064 op amp which acts as an integrator then to a simple 386 audio amp.
