The "Princeton" has been in the Fender amp range for pretty much as long as they have made Amplifiers! A total success from then to now. Of the 6 or 7 versions, this one is the third. A slightly larger cabinet and speaker, with a bit more power,still in great shape nearly 60 years after leaving the Fullerton Factory. Great with a guitar of course and incredibly so with a Harp! Come in and play a few of your Little Walter licks through it and see what you think!
