This has been done before, but there's new stuff on the market as well. Those of you who have used SVT rigs(ALL TUBE head & sealed 8x10" cab, specifically)- what gets "that sound" for you these days? Maybe you have a herniated disk or small car. Can a Sans Amp thru a 1001RB into a Berg NV610 match or outperform the original? Just wondering what your all doing to make it happen.
