Electronics idea.

There are opamps with bipolar junction transistors (BJT) in the input stage.

There are others with junction field-effect transistors (JFET) in the input stage.

There are yet others with metal-oxide semiconductor field effect transistors (MOSFET) [1] in the input stage.

Idea: find an application for the bizarre possibility of an opamp with insulated-gate bipolar transistors (IGBT) in the input stage. This is more stunt-designing than anything practical.

[1] IIUC, "CMOS" opamps are really just MOSFET-input opamps. I'm not sure why the process technology name is more commonly used rather than the device type as is universally used for BJT and JFET input opamps.

It takes a lot of #chutzpah to sell μA741 opamps for $2 each plus shipping.

This will be slightly #geeky, and probably only of interest to #electronics hobbyists and #guitar players. I happen to sit in the intersection of that particular #Venn diagram.

When I was a teenager, having only been playing guitar for a few years, I owned a guitar #effects pedal that went on to become legendary - the Boss HM-2 "Heavy Metal" #pedal. Its sound is still ubiquitous in metal.

I don't have it any more. I think I traded it for an analog chorus, which was a seriously expensive pedal back then. Although I have other #distortion effects, I've missed it a lot over the years.

Well, lots of hobbyists build their own effects. And the circuit schematics for many effects, particularly the classics, are available online. So like many others, I decided to build my own HM-2.

This image is the schematic for the #HM2. It's not the most complicated pedal, but it's a league above something like an Ibanez Tube Screamer. As far as active devices go, it's got 6 #opamps and 10 #transistors of various types, along with a bunch of diodes for multiple types and stages of clipping, and the usual jumble of capacitors and resistors. Oh, and four potentiometers.
