If by "mojo" you mean "overdrive," true. But if you mean "a good clean sound," I don't know...I often run SVT's at low volumes and they always sound great to me.
Yeah that's what I meant.
My main point is that if you're used to playing amps with alot of wattage it's easy to forget how much difference a lot of speakers can make.
My v4bh is the lowest wattage amp I've ever had other than my first 72 Bassman 50.
Not too long ago I too was saying it wasn't loud enough for my band. I added some speaker, decreased the bass a little and added a little more high end to cut thru and now it sounds just like an ampeg should, and hangs quite well with the band.
It does depend what you want. It is not the kind of amp that will supply tons of booty for the dance floor.
100W will give you the grittier tone, 300W will give way more headroom but you might need to be louder than you like for the sweet spot.
It's a tough decision. I love the V4BH but I'm always experimenting.
I have owned an SVT II non-pro and I really liked the tone in the sweet spot but always wanted to find the sweet spot at a lower volume.
Small and Med clubs for my bands. Nothing BIG yet.
