All those were from a different day in a different world, long gone away. Like most, some gems, some dogs, and a fair amount of meh . . . . .
I shudder to think how many of those cabs and the heads that went with them were owned by guys like me 'of a certain age'. They were your first step up into something useable, often on the way to something else.
I'm never nostalgic for old stuff like this, but my first 'real' rig was a Mk2 Bass Head on top of a 215BW bin, and probably my favorite was a the Combo 300 that had that long row of knobs sitting on top of a 115 BW cab, exactly the same size save for the few inches of height for the amp in the top. Those things had the tone of a box of corn flakes, but my goodness, they were loud and you could afford them and you could throw them down three flights of stairs, stand it back up, turn it on and play all night.
That era when Hartley was rolling and Jack Sondermeyer had their products nailed is a time we'll never see again.
