Ampeg V4 B

Post by absolutlytonedeaf » 26 Oct 2017, 12:06

Need some advice on these heads
Looking at purchasing one but just worried about how much headroom it has, I would be putting it through a 610
Thought anyone?

Cheers

The bigger the cab, the louder they are - that's very true in the case of 100w tube heads like the V4B. In recent years I've owned a V4B and the O'Neill B15-100, and neither needed to work very hard at all at the gigs where I ran them in to a 610. Different story running them into a 212 or a single 15 though.

Loudness is in dB, not in Watts. Check the sensitivity of your cab, the more sensitive the less wattage you need to feed it to be heard. The ampeg 8x10 has a sensitivity of 100db. You feed it 1 watt and at 1 metre distance it’s capable of 100db. That’s pretty loud for 1 measly watt

I've used quite a few 100-120w heads over the years.
Volume is not really the issue. It's TONE. Rent one and you'll see what I mean.
The main diff between my 90's SVT and V4 at band levels is simply low end thump. The rest of the tone is pretty much the same or very similar. The low end is there below 200Hz, but it's more controlled, not quite as thumpy as the SVT, and at band volumes you'll have a bit of break up you can't dial out. Some people like it, I do.

I use a Berg NV412 and the V4 is plenty loud for rehearsals or gigs without PA support, but I prefer the SVT due to above.
AussieMark is dead right about cab choice - for a 100 watter I'd want a fair bit of speaker surface area.
