Its funny but the JJ's really sound great in my Wizards as well... despite all the clamor over winged c's. I always used the svets in the past with marshalls, however, I'm happy now to spend half the cost!
This head is blowing my mind. Recorded it yesterday. Just amazing. Switched out the tubes to =C= and just didn't like them as much as the old misunderstood JJs.
