I have just ordered a new custom head. It is a duel KT-66 powered 50 watt head. Similar to a Matamp / Orange / Sunn. Wattage is probably a little higher than listed, closer to 60 or 70 watts maybe. I found an excellent deal on an Orange 4x12 240 watt cab. Is my amp too small to push that big cab? I am considering buying the cab and swapping out the stock Vintage 30's for something else. Looking for tons of headroom, articulate sound with good bass response. Suggestions from those that know are appreciated.
