I got a chance to put an SVT VR through its paces yesterday. . I initially played it through a new Ampeg 810, and used my Sadowsky Metro RV5, and a Fender Jaguar with flats. It's a neat head for sure. It certainly sounds like an "SVT". It has all the volume you would ever need. To my ears though, there was just something missing. Tim Cole showed up a while later, and brought his Eden head (WT400), and his Sadowsky SA410 cab. Now this is almost identical to my rig...I normally use an Eden WT550 and a Sadowsky SA410. First thing we did was plug the VR into the Sadowsky SA410...ahhh....there it is. The head still retained the SVT tone, but was so much clearer and punchier at the same time. If I was going to use an all tube head, it would definitely be through this Sadowsky cab, and NOT through a fridge. The only other cab I'd even consider for this setup would be one of the Berg NV series. Then, for giggles, we thought we'd side by side the Ampeg stack with the Eden/Sadowsky combination. Both of us liked the Eden/Sadowsky better. It had a very tubelike tone, but it was so much clearer and detailed, while still being warm. Although we didn't get to side by side them, from what I recall of my Mesa 400+, I really preferred its tone to that of the VR too. This isn't a slam on the SVT at all, and if I had roadies and was playing really large venues, I'd certainly have one, but for my money, my tastes, my ears, and my gigs, you can't beat the Eden/Sadowsky setup. It certainly helps you can buy a brand new Eden WT550 and a brand new Sadowsky SA410 for less than the price of the VR head alone.
