Vader cabs are a very hard cab to describe. They are very good at taking what ever you throw at them. I have experimented on trying to get my cab to fart/distort and just can't do it. Its not so much the cab as it is the speakers. They are eminence speakers that are custom made for vader, that you can't buy for yourself. They have excellent bass response, a very smooth midrange and a nice mellow high. Really it just one of those cabs that you have to buy out of hope that it sounds good because unless you live near wisconsin, you can't try before you buy. I used to be a straight up celestion man but these speakers have changed my view on things
To be honest, I have never heard anyone say a vader sounded bad, no matter what amp they played through it. So yeah, that's my PSA for vader for today.
If at all possible, get you a vht ultra-lead with a bloody murder. I think that vht should pay joe to include them in there amps from the factory. It is just insane how awesome they sound together.
So let's recap:
VHT ultra-lead + bloody murder + vader 4x12 = what you NEED
