Cool amp Stefan, you always seem to turn up some nice gear. I was looking at a couple of similar ones recently an '81 and '76, both Silverface. In fact I just checked to see if the '81 was still for sale as I wondered if that was the one you bought, but I guess not. I also saw a (birth year for me) '65 Blackface one that tempted me. I have a little 5F1 'clone' which only has the single volume control and I've been very impressed with the sound it gets, so can only imagine how a proper Fender would sound.
