Hi all,
 
	 are there any deivices , units that can change the ohm rating before you come out of the amp..or in?
 
	 
 
	bassically i have two 4 ohm cabs and the amp only goes to 4 ohms meaning i can only run one cab from the amp?
 
	 
 
	im a complete mindblock with ohms i just dont get it.
 
	i have a ebs head that goes down to 2 ohms so may just use that , but wanna use my new head as it sounds sweet.
 
	 
 
	any thoughts ?
 
	 
 
	kindest regards
 
	ziggy
