$4    Voltage-Controlled Resistor PCB


For use in circuit-bending, or modifying circuits with a variable resistor.

The resistor is only affected by positive voltages.

Uses two pots -- one for initial control, one CV attenuator.

Can use single or dual vactrols, which we also sell.

Has optional range-trimming resistors.
