You may smoothen the volume response by turning the volume knob counterclockwise. If that is not sufficient, you should slightly increase the frequency of the volume oscillator. This is done by adjusting L11. If it's the old model with the "normal" slug turn it 1/12 turn wise counterclockwise. If it's the newer variant with the hexagonal slug turn clockwise.
Close the cover after each tuning step, let the instrument warm up for a few minutes and turn the volume knob to its center (12 o'clock) position. You are done when you obtain maximum volume with your hand around 6"/15cm above the volume loop. Then check the operation of the volume knob without a hand near the volume loop by turning it slowly counterclockwise. The max volume should go down when you are around 9 O'clock. On the other side beyond 3 o'clock, the volume response should be snappy again. Then you are able to adjust it perfectly to the desired behavior within these positions.
Tuning the pitch side for best range and linearity has already been discussed in public here on TW. In one of the ESPE01 topics you will find a conversation between Thomas Grillo, Wilco Botermans and me, containing lots of practical hints from experienced "tuners" which give far better results than Moog's original tuning method.
@Christopher: thank you for the expression "male Rottweiler that is running loose"! Couldn't have found a better picture by myself.
