I am getting an Eminence EUB and I am also wanting to purchase a small battery powered amp to play through for bluegrass jam sessions. I know that the PJ Briefcase is the best portable available but I don't want to spend $600 for it. I am considering the Pignose Hog 30($160), Fender Amp Can($175), and a Crate TX30BE ($250). Which would you recommend for sound quality and battery life.
