^^^THIS, THIS, and more THIS^^^
I have seen a significant number of TB'ers talk about how the 100-watt version doesn't provide them with quite enough headroom and the 300-watt version is overkill. A 200-watt SVT/V4B would be the goldilocks version to fill that gap. Of course, there will be plenty of folks who will chime in (as they have done in the past) and provide reasons why a 200 watt SVT/V4B isn't necessary or doesn't make sense. Those comments certainly have merit, but even so, based on other comments that I have seen over the years, there is a desire for a 200 watt SVT/V4B.
I'd like to see a 200 watt tube Ampeg bass amp. I had a 200 watt Marshall Major years ago and loved the thing, wish I still had it.
