Just got a new AC 15. Limited edition with the G12 cream back. First real tube amp. I had my heart set on a deluxe reverb for the last while but tried one of these and was surprised how great it sounded. And then when my brother called me from a guitar center in seattle with a too-good-to-be-true deal I had to jump. Loving it so far and curious about what kinds of upgrades y’all have done. Speakers? Reverb tank? Tubes? Flux capacitor?
