Is there a way to electronically adjust the delay time on a reverb circuit that uses a spring reverb tank?

On reverb units that use IC’s you can adjust the delay time by changing resistor and capacitor values.

On reverb units that use a spring reverb tank the delay time appears to be a function of the spring length.

Is there a way to add a potentiometer or variable capacitor to the circuit somewhere to make the delay longer or shorter?

    Using spring to create delay sound effect is a very old technique and the result is not well at all. Since the length of spring is fixed in that special made parts, therefore no way to change its delay time. Modify the spring length and tension is the only way.

    As others have said you can't do it electrically. You might decrease (decrease) the delay time by increasing (decreasing) spring tension. However I don't think that's a good idea as the spring probably would be damaged by increased tension and decreasing the tension would probably add distortion.

    No, the delay is set by the LC values of a spring. It cannot be altered electronically without lots of redesign.

    probably not, but I'd have to see the schematic and spend a lot of time analyzing it to be definitive.
