Hey Mojo and JimBass,

My recollection is that wire-wound variable potentiometers (so-called L-pads) that have continuous adjustment are considered a no-no for hi-quality applications for reasons that at this hour on a Saturday morning, minus my third cup of coffee, I can't recall

But it's likely the reason that the stepped ones are a much better alternative.
