I'm looking at an old schematic for an amp from the late 50s. It has several pots for vol and tone specified simply in terms of resistance (i.e., taper not indicated). But the depth pot for the tremolo is specified as "350K Left Hand Taper" I've read one or two references indicating that this means audio taper...and then I've seen guitar pots that are called "Left handed pots". If this means audio taper...do you think that they were using linear taper for the other vol and tone pots? So anyone know what's meant by this term, left hand taper?
