I've found a NOS Ampeg V4BH for sale. I'm trying to get an idea of what differences there might be other than cosmetics. This one has the black tolex with "Classic" type grill cloth and white piping. The printing on the faceplate is white except for the legends around the knobs and the script V4BH logo are blue. Later pictures I've found on the web have all of the printing in white and the V4BH logo is done in a block type.
