I'm looking for a small, lightweight (under 30 pound), low power (~15W) combo amp (1x12) to tote around for jams and practice sessions. I prefer tubes over SS and lean towards a Fender or Vox vibe rather than a Marshall/Mesa high-gain sound. Onboard spring reverb would be nice-to-have. Musically, I play classic rock and blues. Reading the TGP forums, I've looked at some of the boutique brands, but their 15W amps are heavy at about 45-50 pounds (Vox hand-wired AC15, Matchless Lightning/Spitfire 1x12, etc). Any suggestions? Thanks!
