Finally got this voltage-controlled resistor working in a small test circuit—the way the top sprocket voltage directly lowers bottom resistance is incredibly responsive. Makes tuning way more precise than I expected.

Slapped this into my breadboard rig and the resistance curve tracks the top sprocket voltage way more smoothly than the old setup. Dialing up the gate voltage drops the bottom sprocket resistance exactly like the spec sheet says, no weird jumps.

Didn't expect a voltage-controlled resistor to behave this linearly, but the resistance on the bottom sprocket drops smoothly as I raise the voltage on the top one. It's been a solid little extra part for my bench setup.
