Could Fender make so many PRIIs, considering they were making another 13 amp types in the range at the same time?

Then Soren in Denmark started showing serial numbers on his excellent Super Champ website, recently gone off the web - some of those numbers fell in between some of 'my' PRII numbers.

While it's anyone's guess how many of these were Champ II and how many were Bassman 20, they seem to come up on e Bay equally often. People keep on referring to this 'fewer than 500' thing, especially when they're trying to sell one as 'rare', but I'm still waiting for anyone to point back to the original 'fact' of the matter!

latest updates; small changes to a few amp batches dates, Dec 2015, Feb 2016, July 2016, Sep 2016 small changes to 4 amp batches, Nov 2015 typos found, two edits, thanks Ben H, June 20 info updated, totals unchanged Oct 2014 really nifty table design Aug 2014 small data and totals updates Jan 2014 (info updated In 2002 I acquired a Princeton Reverb II. Fender don't part with that kind of information*, so as part of the website I developed for this amp's care and feeding, I put out a call for serial numbers.Eventually, I thought, I'll get a rough idea what the highest and lowest s/ns were.It represents ten years of hobby time, so if you quote it elsewhere, I'd appreciate a link and/or a name-check, either as "Stratopastor" or under my real name.All these amps have serial numbers beginning F2, F3 or F4 followed by another 5 digits. However Fender couldn't maintain that system for long, and there are no F5 or F6 amps.I run a couple of websites making the schematics for these amps easily accessible.

As people download them, I'm hoping they'll respond to my request that they send me their amp's serial number for this project, and many do.

This in turn means that these 2 amp types can only be treated together for dates or production quantities when, as in this study, the serial number is all we have to go on.

(Fender did this chassis-sharing thing in earlier years, with the same implications for guessing quantities, as noted by Greg Gagaliano.) I estimate about 5500 were made in total.

One run of Princeton Reverb II serial numbers seems to stretch from 1984 to 1986 with just a few from 1987, yes 1987, when some 220V models were still being sold in Sweden.

So if you'd like a bit more detail on an amp in that category please get me some date codes, not just the serial number. Upon arriving at Fullerton, any one of these chassis might turn out to be a Champ II or a Bassman 20, in a process which appears semi-random when tracked only by serial number.

Certainly the hundreds of people who have helped me seemed keen to know.
