I read the other day somewhere and I guy said he liked to use a Sansamp Bass Driver in front of his SVT to drive the amp. Do any of you guys do it? Is it cool? I see there's the original one and a 3 channel programmable one, any sonic difference? I ask cause I have a '78 SVT and it sounds awesome but sometimes I want some more stank on it with my Nash P Bass. I tried my Maxon 808 and OCD this week and no matter how I set them they was to much gain. I'm just looking for more growl and note definition. I was listening to an old Rush live video and you could hear every note so clearly on Geddy's rig. To me it sounded more then just good playing chops. It almost sounded like some slight gain in the signal path. ???
