back in the days of pc boards and splices... When the circuit required an operational amplifier, you stuck a transistor in parallel with the base and collector and that was it.

so I am buttoning up my new monster guitar.

I don't know how I got it all on that one little chip...
Or how I am going to get all the wiring in the cavity...

But it is producing some real wild wave forms on my automobile scope...

I need hear some gargling from the masters though....

I am attaching a little pic for you to visuallize.

I remember a couple things about this op amp thing, the first one is that if you have a chip use it, and the second that it requires some kind of buffer....
well maybe I don't remember so well !!!

My little OP amp isn't all there...
I can't remember where the resistor went, or what the formula was for getting the value...

Do you have any idea what you're talking about?

Because we don't.

He is calling a voltage follower an op amp.
