Title: Dating my Fender amp
Post by: navdave on August 18, 2010, 05:20:17 pm
Having trouble trying to figure out when my Fender Prosonic was made.
It has a serial number of CR-270365. According to the Fender website it should be a 92
but that cant be right these amps were not in production til 95.

The date code is not in the serial number,it's on the quality assurance tag.It's the last digits,not the first like the serial number.

The only sticker inside the chassis is the assembly sticker line four says CH hard to read the other three lines.
CH is August 1992 that cant be right.

I thought you wanted to date your Fender, like take it out to dinner and a movie......I mean I had amps I really liked but I never wanted to date one. Well there was this Blond bassman.......Big Bottom and really thick on top, nice mid too.

Sorry I couldn't help it...... :angel

There should be four digits after the 606 manufacturer code.

a suggestion - go to fenders website and support section and give them an email and ask if they can help - I've had very good response doing this...

You can also look at the pots for date codes. It's a similar scheme to the transformers, with fff-yy-ww. "fff" is the factory/company code, the next digit (or 2) is the year, and the last 2 digits are the week.

Or you could just guess mid-late 90's and likely be close enough.
