hello. would i be able to power a small cab through the line out on this amp? seeing as it still plays when something is plugged into the line out, i thought i can power a cab with it. can i?
Nope, you need the proper outputs for a cab. The Line out is to plug in headphones or into a mixer.
+1, the line out isn't at the proper impedance to power a cab.
Besides for the price of a decent cab, you could upgrade your amp (Providing you're not happy with the GRCD)
