I wonder how loud an old Ampeg v4b and an Ashdown 103dB SPL 410 would be. Previously I have run a 300W/410 trace elliot combo and that was enough for me. Is the v4b louder??? Will it be enough for small clubs and partys or even larger clubs? What do you think of the possability to ad an active sub to an old tubeamp to make it louder?
