LOL yes sir David, and thanks to your excellent advice as always this stack rules as h*ll. I'm sorry I no longer use Ampeg for cabs, but my old tube amps definitely drive these 1500 watts taking babies straight to heaven. You won't believe the lows, definition, pressure, and tube sound they deliver. Plus the 210 and 310 give me unlimited flexibility for al kinds of situations. It took some time to find and test the 'right' cabs for what I wanted (low weight, high power, deep lows, small size...) but I'm all set till the day I die. And - David: no discernable volume difference with the V-4B at 2 Ohms. Can you believe it? I'll report again when the SVT arrives.
By the way, David - I'm doing the J-thang normally, with the amp on its road case next to the cabs - so join the club!
