Does anyone know how I may obtain info on vintage Ampeg combos?!?! I have been blessed/cursed w/one that seems to be @ least thirty years old. I dont know much about it except that it is inoperable! I was hoping that I could find out if this rig is worth restoring. I currently don't have the model # in front of me and I won't have that info until this weekend. I do remember that it was a 410 300W model.
