It would be interesting to try adding a resistor directly across the amplifier input (slider to ground on the pot. About 3K3 or 3K9 should be about right. This will make the control more logarithmic and make the volume a little easier to adjust. You generally use 12% to 20% of the pot value depending on the impedances so it's something to experiment with. You may lose a little output with the lower values.
