Negistors - negative resistance transistors

The theory is a bit above me to explain, but the application would be an oscillator (?)  effect for guitar, or something like that, using 3 "negistors" in series

Tl dr; the currents are going the wrong way!

Fluorescent bulbs have negative resistance. Within their operating range the resistance is indirectly proportional to current. Maybe your should run your guitar amp through some bulbs.

I would think true negative resistance would be essentially a power supply.

Fluorescent bulbs are a positive resistance because they absorb power.

Look it up, the actual terminology for electrical and electronics. That's why fluorescent bulbs need a ballast, to limit current flow. Positive resistance is not defined by power absorption, nor negative resistance, as both are descriptions are how current and resistance react to each other.

There is no 2 ohms + -1ohm = 1 ohm. Only a power supply can exhibit these characteristics.

You are referring to the differential resistance (dV/dI), not the absolute resistance (V/I). There is a nice circuit by @hurz that shows true negative resistance out there
