||Tweed amp Lacquer|
This past weekend I went to the guitar show at Pomona Fairplex and noticed how the old Tweed amps had lacquer on them, some of them a pretty thick coat. I own 2 tweed covered amps (a RI Bassman and a blues deluxe) that I would like to protect. Sometime ago I remember seeing a post on how this can be done. Anyone have experience lacquering tweed? Thanks in advance.

I saved this post last spring...worked great on my bandmaster converted blues deluxe.

I have applied the amber shellac to new tweed, as the method supplied by Dave. This gives the correct aged color, but not the same texture or gloss as seen on the older amps.
I looked closely at an old tweed Deluve amp, and noticed that the finish was fairly smooth, somewhat glossy. I believe that the factory finish was just multiple coats of clear lacquer (at that time, probably nitrocellulose), just like the finish on typical suitcases of that era.
In order to mimic the early finishes, aged to the darker color that we see today, two things need to be done. First, apply the amber color coats of shellac until the cabinet covering looks as old as you prefer. Second, apply multiple sprayed coats of clear lacquer so that the surface texture is considerably leveled. I don't know how much (how many cotats) of lacquer is sufficient, yet. It probably requires a lot of lacquer. That stuff was cheap in the '50s. Not today, of course.
Did you notice that the fender amplifier tweed cloth is already sealed with some type of clear finish? Probably to resist soiling and fraying. The custom shop tweed guitar cases come covered in the same cloth, but the vintage reissue (and purchasable accessory) cases are covered in a different, untreated cloth with the stripe pattern going in the wrong direction.

Thanks Dave and Doc
My primary reason for lacquering the tweed is to protect it from liquids etc. I did see some recovered tweeds at the show that had been lacquered quite a bit but the lacquer was clear, i.e. the amps looked new until you looked in the back at the cabinet and speakers.
