Actually, that is a good point. The last Ceegar box I made had 66 steps for each channel! The pointer knobs helped. I built it as a buffer amp and so you could find the volume you wanted, and send it to the integrated amp to get the right amount of 'dial' for the master volume. In my latest iteration of this project, I have chosen a stereo volume control with stepped attenuators for L/R channels. This way only 36 steps, and easier by way of the stereo(master) volume.
