Hi! I am planning of getting one of these cabs, I could get them at the same price. I will pair the cab with my GK1001RBII. I am looking for a modern rock tone, for modern rock I mean something a bit more defined than the classic svt + 810 tone you hear on sooo many recordings, so I guess the GK head with one of these cabs could be a good idea. I tried the GK cab and I found it nice, anyway I could not push it in the shop. I haven't tried the ampeg yet, so I would like some feedback before going around searching for that cab to test. weight and portability are not an issue to me, I am only interested in TONE and VOLUME. The GK is 8 ohm but the sensibility is higher than the ampeg. The ampeg is 4 ohm but it's rated at 500 watts, I don't know if it would be a good match with the 700w GK head. What cab would you choose?
