Busting the myth of magical op-amps and diodes...?

Everyone knows the the mystical 4558 op-amp IC chip is responsible for the best overdrive tones right? I mean, even Stevie Ray insisted on it in his pedals, am I right? Right?! Joking aside, I dive through several popular op-amp IC chips and show you what each one sounds like in the context of Guitar Overdrive Pedal Circuitry. Well, not every one out there, but some popular ones... from $.20 IC chips to $10 versions of the popular Operational Amplifier Integrated Circuit chip. And just for kicks and giggles, I'll show you the difference between several types of diodes, and the difference when running it as a soft clipping overdrive to a hard clipping distortion. Sounds like fun, eh? Oh, and I realize the title is a little click-baity. But it's all in fun, am I right?
