i just recently purchased a new ampeg 6x10 HLF to go along with a relatively new gk800rb.. the 6x10 is rated at 600 watts, and the gk output on the main head is 300w (i'm not currently using the 100w output at 8 ohms, but from what i can tell, this shouldn't be a problem).. while the cab and head are not perfectly matched, i figured that they should be compatible with no problems. however, i have noticed that the clip light (or something akin to a clip light) tends to be activating whenever i play highs, or manipulate my delay pedal to start sending out runaway delays. this seems completely peculiar to me, given the power handling of the cab. unfortunately, i've had to alter my tone (which is typically quite treble-y, with a fair dose of gain, but still maintaining some low end) to compensate, and reduce the (supposed) clipping. i don't want to exhaust the speakers, but also feel that the cab should be able to handle the output of the head.. anyone have experience with this? how did you resolve the issue? thanks in advance!
