I've had my '74 Ampeg VT-40 for about a year now and still digging it. Vintage 60 watts, 4-10" "poor man's Super Reverb" for only $299! With a Tele or Strat it sounds very Fendery, and with a LP type guitar, the mid-range will knock you out. Also love the groovy tone controls with huge range and the nifty switches.
Am I the only one...? :)
The dang thing's painfully heavy, though!
