A friend built me a module for precision voltages

I wanted (for live situations) direct access to more then one parameter (without using the ‘the knob’ for more then one parameter). A friend of mine built this friend for the ER301. It is a module with two 10 turns potentiometer, with current as outputs, adjustable at the back (-5 - + 5, 0-10, 0-5).
Very nice to get very precise values ​​and sweet spots from the ER301 (for me the place in long samples) without using the big knob. Very nice :slight_smile:
