Mine had an AX7 and an AU7. I changed them both for electro harmonix AX7s to get a little more break up in the pre. However, I don't know what they have in them nowadays - this is one of the earlier, UK built amps.
I actually love the eq; ok, it's not the most versatile but it's passive, and set up right gives a lush thick tone. The one thing I've noticed is that the bass and mid shifts completely change the character of the amp - with them off it's voiced in a similar way to an orange or marshall, but engaged it really does get into svt territory. I guess it is a bit of a one trick pony, but I'm pretty bloody fond of that trick.
