I have 2 Hartke 410TP's which make an 8x10 alu. coned monster which I love. Problem is the Ashdown Superfly I just bought has a fault that can't be fixed so I'll have to return it to get a refund. But my question is should I get a head that has better tone and less power or a head that has more power but not as good tone. The 2 heads I were thinking of were the Markbass Little Mark 250 (250w at 4 ohms) or the Peavey Tour 450 (450w at 4 ohms). How much difference would those 200w make at a gig or practice? Cheers.
