57 Champ Reissue Vintage pkg
Would have never believed a tube upgrade could have made such an incredible change in this amp. It sounded great, it now sounds outstanding. Fantastic buttery tone and turn it up and it will get beautifully nasty as well. The JJ 5Y3-S was changed to an NOS RCA for better longevity for marginally more $, but well worth it....Thanks TubeStore staff!
