It looks like a wide cabinet, like the 1000 series.
It has the larger black name on it, like the 1000 series.
If it has reverb and tremelo, wouldn't it have more knobs? I thought some 1000 series amps had R&T
Could it be a 350L? I have never seen a picture of one? If it is, it is my understanding from readings that the 350L was a 1200 in a new package. Somewhere on this forum is a posting where someone mentions a picture of one.....have you searched this forum for "350"?
Any chance you have the picture in higher resolution? I can't really tell what the numbers are from your posted picture.
