Proco rat serial number dating
Numerous variations of the original RAT pedal are still being produced today.The basic RAT has changed in appearance over the years, but its tone has remained largely the same.Some early DOD FX-series pedals have stickers with the date of final assembly, but unlike Boss pedals, the month and year of manufacture is not encoded in its serial number.However, like vintage guitars and amps, the date of manufacture of almost any effects pedal can be estimated by examining the date codes of its components.Almost all IC chips have date codes, and other components such as potentiometers, transistors, and electrolytic capacitors can also have date codes.After opening up 175 different DOD pedals and examining the components of their circuit boards for date codes, we plotted serial number as a function of the latest component date code found in each pedal.P Recordings: a quick check at Amazon shows a number of CD's, several of which look pretty darn enticing! Amp: Well, by deduction/process of elimination - gotta be a small-box Tweed Fender or Gibson amp.Either way, sounds like 6V6 tubes (the heart of both amp types) - great just-this-side-of-breaking-up tone, saturated and articulate. As an aside: I wish more guitarists took the "less is more" adage to heart, especially when it comes to distortion/overdrive.
Players don't realize that their heroes typically dial in much less gain - it just sounds big because that just-overdriven tone cuts through so well.
Thus, be sure to include the leading "1" in your pedal's serial number when it is present.
At the beginning of 1983, serial numbers appear to abruptly step up to 200k.
We had never seen a DOD FX-series pedal with a serial number between 117k and 200k, until Jeff Kehoe sent us photos of his FX25 (SN 118400).
It is possible that others may exist, probably closer to 118k than 200k.
Note for guitars without a serial number Up to 1977 there was just a label inside the guitar with the last two digits of the year in the bottom right hand corner (see example on the right).
