So I posted here recently about acquiring an Ampeg SVT 6 and not being too sure about it. Just thought I'd share my recent findings. I returned the SVT 6 and bought a used SVT 3 for about half the price. WOW. The SVT 3 blows the 6 out of the water for nailing that vintage ampeg tone. I expected the 6 to just be a more powerful version of the 3, but they are in totally different leagues. The 3 has plenty of headroom, I actually have a hard time believing that it's only 450 watts. The 3 is a lot lighter, and with the money i saved I might even go out and pick up another P bass. I found the compressor on the 6 to be pretty much unusable since it has no controls other than just level. And other than that the 6 just offers more power and a parametric EQ. The 3 has plenty of adjustability with the graphic EQ so the trade off is not really much of a sacrifice. I'm not saying that the 6 isn't any good, but it's just voiced much differently and has that more "modern" sound. I was looking for a small solid state head that came close to the tone of my V4B, and this definitely the one.
