Yes, looking at the knee levers it's definately my first ZB.
If it has not been altered from my setup, it is a very easy-playing steel, as I had festooned it with helper springs etc.
I gigged it for quite a while, it had a fantastic tone, but suffered from quite a bit of cabinet drop.
I'm a bit older and more experienced now, and could probably get around the cab drop problem with various methods that I have devised in more recent years
My wife wanted a new stair carpet at the time, so I had to sell this ZB to fund it
