I have the Custom Vibrolux Reissue and it's hard to beat but it depends on if you want clean or saturated tones from your tubes. The Vibrolux is loud and clean but will break up right after your ears bleed. The DR breaks up at a more manageable volume but is still plenty loud. The other difference is the 6V6 vs 6L6 driven power amp. Different sounds. Most blues guys I know swear by a DR. Might be your best bet but I would definitely upgrade the trannys to Mercury's and have all the caps replaced with something sweet. BIG DIFFERENCE. My Vibrolux is loaded with Mercury's and F&T caps and there is nothing like it. Better for country than blues. Now I'm just rambling and thinking about my amp...must go play...
