I first saw Kustom amps when I was about 12 and I am 60 plus now. I never forgot that and finally purchased one yesterday. By the serial number I know it was made in 1970 thanks to your list. The model number can't be read but the front panel looks exactly like a K-50 only there is no number on mine where the 50 is in pictures. It has 1 Jenson 12" in it. What would be the easiest was to determine the Model number?
I did plug it in when I brought it home yesterday and it sounds great. Thanks in advance!
