Hi everyone! First post here but I have been a reader for a long time. I don´t know if anyone asked this before and if it´s already been asked, please excuse me. My question is: I currently play a Rick 4003 through a JCM900 + 1960 cab and I get a GREAT tone. But there´s a possibility of getting an Ampeg SVT CL. I´ve cheked their impedances (head +cab) and they match but unfortunetly there´s no chance of putting amp+cab together before buying. So, is there going to be any issues on this combination? Any mismatch issue on impedance or wattage? Many thanks for any info or help. Cheers! Diego.
