While I sit here on pins and needles waiting for a '60-62 Concert to pop up thought I'd ask a few questions that have gone unanswered. First of all, amp hunting sucks! Every concert Ive played varied in tone (which could be due to speaker change, tubes, caps etc) The early ones with the yellow Astrons either need to replaced or have a tendency to leak or be out of spec. Anyone compare the astrons with the blue molded Mallories? The 1962 model with the stock brown Fender spaghetti logo Oxfords, do they hold up on the low end when pushed? Its been described as a hybrid: BF Super Reverb meets a Tweed Bassman able to get a Marshall crunch when cranked. Would you say thats an accurate description?
