I am currently using a warwick corvette standard w/active pickups and running it through a GK800RB w/2 peavey 115BVX cabs. It seems that the signal from my warwick is way too hot for my amp and distorts my low notes. I have my low cut filter on, -15db pad and bass turned down , as well as my preamp disabled on my bass. After all of this it leaves me with having to turn my amp up all the way and still am too quiet. If anyone has an idea or have run into this problem with warwicks, please let me know. Ive also had everything checked out - bass, amp, and speakers are working fine.
