Do any of you fine people have any experience with the Fender Princeton reverb reissues? What are your thoughts on it? I believe the speaker can be the weakest link unless it's a limited edition with upgraded speaker, what speakers would be recommended as an upgrade? I really like the look and sound of the Knotted pine ltd edition with the creamback speaker, really warm sounding. So, your thoughts are much appreciated and I thank you in advance for your time and help.
