So shopping around town and I find a 1973 Ampeg flatback 810 for $300 bucks. It has original CTS speakers BUT the toltex is completely gone and its painted black. I can deal with not pretty but is this major issue? How bad will it affect sound or durability? Any advantage to an older cab because there are newer ones around me for $450 bit $150 bucks is $150 bucks. Any advice is appreciated!
