So I have the opportunity to get these 3 heads for roughly the same price but I'm having a hard time choosing which to get. B200H sounds great. Never played a B300H but it sounds similar to the B200H, just more wattage and footswitchable overdrive which is a plus, but the quality may be suspect. There's very little info about the 450 (never played it) but everyone says vintage Acoustic heads are great and reliable. What should I do?
