Hey fellow talkbassers. I recently moved into a new home and the former renters left an Ampeg B-15N amp and 1x15 Cab in the garage and apparently they don't want it back. Yay me right? Well I was just wanting to get some info on this amp. What year it is, etc etc. It was pretty filthy when I got my hands on it, it looks like it hasn't been played in a long time, but it works great. As you can see in the pictures under where it says Serial No. is scratched off. Any info would be awesome, thanks!
