Howdy Folks, sorry if this has been covered but I’m on a mission and didn’t take the time to search. Hope you’ll help me out. I have a Fender Princeton Reverb reissue with the tweed and a Canibas Rex 12” speaker. Bought it new and I just haven’t fallen in love with this thing. Yes, I know, it’s not a Marshall Thinking about putting a new (China) Greenback in it and see if it comes alive. I realize the new Greenbacks can’t be as good as the old ones made in jolly old England, but how bad/good are the new ones? They run about $125 and if that makes me love this amp, I call it money well spent.
