OK so I picked this baby up!
Very amped about it! After alot of searching, I found out that the speakers in there are 4 x Celestion Super 65's... Not the most well known speakers and only made for a limited run and rebranded for Hughes and Kettner as Rockdriver ultra 65's
edit: the model of the cab is a Hughes & Kettner SC 412
Sounds good... alot smoother than the G12T 100 i have in the combo.
But something weird happens when I plug the cab into the 'External speaker' plug of the combo... the combo's speaker works too. I thought that it would cut out?
And also, the cab is 8ohm and the combo speaker is 8ohm so now we're down to 4ohms if both run... or am I missing something?
