I have a Peavey Combo 115, now with both the pre gain and post on about half, the DDT speaker protection light pretty much stays on while im playing. Which the manual recommends against. Now i wanna push my amp a bit further and extract a squeeze more volume out of it, but am concerned about blowing the speaker. My bass seems to be a tad louder than most others ive plugged in (mine isnt active). Any ideas how i can get more volume without pushing the speaker to hard??? I pretty much have the eq flat.
