My first amp, (in about 1969, or 1970) was a Fender Bassman head, that was dark brown, (I think), and a newer Fender 115 cab. The cab was not that great. I played with some guys with very loud Fender combos, and my rig was inadequate. One guitarist played way too loud, and my cab would fart out like crazy trying to keep up. I don't think he noticed, because all we could hear was him. He was a very good guitarist though, and I sucked, (still do), so maybe it was all for the better that I was drowned out.
I think my dark brown colored Bassman head was maybe a 1960 model, but I don't really know.
