I recently upgraded my practice amo from a VOX DA5 to a VOX Valvetronics VT20+ (not to be mistaken for the VT20) difference being choices of modeling amps settings ) So far I like it but have not played with it alot yet. On the VOX website it shows all vox amps and reccomended setting to accomplish various sounds mimmicking differnt artist. Pretty cool but I am looking for more choices in blues settings that can give me just the right old school Muddy Waters, early 60's BB King type sound anyone out there would have this amp and dig the blues that could maybe give me a good setting for that I just cant seem to get it right. ???
