When I called the retailer who sold me the amp, he told me that the "body"
control was the equivalent of a mid tone knob, but it doesn't seem to work
that way on my amp. When I roll the "body" knob down to 0, the tone is very
thin, like a cheap, old, transistor amp. When I turn the body up past 7, I
get a lovely springy sound. I am happy with the body up, along with the
expand switch activated, but I would have liked to be able to manipulate the
mids.
The "body" control even has more effect with the Depth switch up.
