All-original except grounded plug (original gray cord included). Big brother of the tweed Harvard model, one of the most recorded amps in history. Here we have a vintage 1964 Ampeg M-15 "Big M" combo amp.In excellent condition with the original footswitch, loaded with the original Jensen C15N, dating to the 36th week of 1963. Here we have a 1964 Fender Bandmaster head and matching 2x12" cabinet.Fender introduced the Blues Junior in 1995, and has revised and updated it periodically since then.
She’s tube rectified, for nice early sponginess, and she does not quite have the huge trannies of say the blackface Bassman or the Super Reverb, so again, she gets juicy a little earlier, but she DOES have enough clean headroom on tap for a loud club date, unlike say a Deluxe Reverb.
She IS about the same size as a Twin Reverb, but with half the power section and WAY smaller transformers, she’s a LOT lighter!
2006 amps have a small metal “Fender 60th Anniversary” button on the back plate. Early Tweeds The early green board tweed-covered amps were not lacquered. It has the same cream board inside with the same components as every other current-production Blues Junior.
The serial numbers for these amps begin with “LO,” indicating that they were made in the Fender/Sunn Lake Oswego factory. It usually applies to old vacuum tubes/valves that have gone unsold for decades. All cream board tweed Blues Juniors have a “Limited Edition” plaque on the back.
and she’s giving the Super a real run for the money!
The Pro is an amp that has all the right stuff to be a fantastic club amp.
All green board and all cream board Blues Juniors are identical electronically, despite what the salesman told you. Below is a table of revision dates and the changes made on those dates. Fender adopted a two-letter dating code in 1990, and the code can be found on the Quality Assurance label, inside the cabinet, sometimes located on the bottom, next to the reverb tank, sometimes on the side.
The codes are usually handwritten, and the letters can occasionally be hard to decipher. There is no reliable way to date 2003-2005 amps other than to ask Fender customer support to look up the date from the serial number, although you may find a date code on the speaker.
I'm new to the forum, found it by searching for help on solving a problem with my amp.
