I have a gig tonight, I am using Ruby el34's and 12ax7's, the amp is a Hughes and Kettner Duotone. I am using a paduak and curly maple custom hollowbody w Duncan 59 humbuckers, I think this paring is kinda bright and metallic sounding, what differences can I expect if I put a jj in v1 and v2, I have 2 new jjs lying around but Icant try them out before the gig w the kids running around. Will this smooth things out a bit better than the Ruby preamp tubes I have? Thanks.
