| Your V4B has an ohm selector switch (2, 4 or 8) you set to match your cab loads. The amps max output level is the same at all of its ohm settings, so you could could choose 4 or 8 ohm cabs.
You could run one or two 4-ohm cabs,
or your choice of 1, 2, 3 or 4 eight-ohm cabs.
ps:
If you think you might upgrade to an all tube SVT to be used with this cab at some point in the future... I'd suggest you choose 4 ohm cabs now.
