I had an 80's NS2 with the hazlabs circuit, and it was fabulous, really grunty, throaty honk, great bass. I also had a couple of Euro 4LXs and they were fantastic too. Beautiful build and ergonomics, and tone to die for.
The only one that I didn't quite get on with was a Euro 5. Same quality of build, but it was so "in your face" tonally with the tone pump on that one, that I just couldn't dial in the tone I wanted. It was the non adjustable EQ version, maybe that was the problem, don't know.
I've always thought of Spectors as kind of like, riding a rodeo bull. You just don't know how long you can hang on before it throws you off.
