Ahh... one of life's eternal questions! I am not sure if even the Music Man catalogs I have make reference to this (the answer doesn't immediately spring to my mind, anyway).


The standard joke is that "HD" stands for "Horrible Distortion".


My guess is that it stands for some marketing tagline like "High Definition". The HD models are strictly higher-power versions of of the standard models and have 4 output tubes instead of 2.


HD models started out in 1974 as 130 watt RMS amps. By 1980 or so they were upgraded to 150 watt amps (hence the model change to HD-150).
