Right now I am using an Ampeg SVT-350H through and SVT-410HLF cab. I love this setup and it works very well for me, but recently I have began to wonder about the V-4BH. I have been wanting an all tube head for a while and I was wondering how the volume levels of these two heads compare when plaing them through the 410HLF. What about the 610HLF? I did a search but I couldn't find a definite answer, so I'm just looking for some opinions. I'm really not looking for other recommendations or anything. I'm set on Ampeg and if the V-4BH won't cut it then some day I will have to get the SVT-CL. Thanks. Oh and I have heard how great the vintage V4's are but I'm really not interested in those. I'm talking about the new model.
