I get the original cl, heritage stuff. What about the III's, IV's etc. ? Here is my point........... I would like to eventually move to a fridge set up and I love the SVT sound. I don't like the weight or expense of a true SVT. I would be happy if I can get close to that tone and have been eyeing the SVT 7! Can someone break down the pro's and cons of Post SVT stuff? Thank you.
