I'm still using my Marshall 90's rig for large shows with 1 or 2 410s (dependant on how far I have to carry them lol)
It sounds absolutely immense and the 7400 dbs is the only head I've found that can deal with a wah pedal properly.
For smaller shows where I don't need wah, I use a TC bh250 and 410, but it does lack some of the heft (LOL) of the Marshall.
I used to have a Hartke LH500 which was great, but I never really got on with the eq
