MM 112-RD 100

Scored a 112-RD 100 to play my Jazzmaster though about three months ago and have enjoyed this amp ever since. Picked it up relatively cheap in Santa Barbara. The outside is a bit rough (missing tolex) and the cabinet has been spray painted black :( . The grill cloth is the same as the silver face Fenders, but what puzzles me is the emblems. The emblem that states the type of amplifier says 112-RD is in black letters with silver backing (earlier type), and the MM logo is the later version (silver on black). Can't find the serial number table on the internet to find out what year this little gem is actually from. The only issue besides the tolex is, the bright switch. When switched into the bright mode there's a crackle or, static when letting a note ring out (thats the best description I can come up with). Other than that, I love it. Great cleans, and an awesome pedal platform.
