For the Control Denied album both Carvins, fretted and fretless BB75s were used through an Ampeg amp and some easy preamps for the direct sounds. A bit more midrange than the Death albums, a little cleaner than the Sadus stuff and kinda close to the Vintersorg setting for the bass. It's really simple, I always keep it simple. Just try and get the sound of the bass with the least amount of electronics. And yes...it's all in the fingers!
