I just picked up a Sansamp Bass driver ,small box version. Its not what I am wanting. I have a SWR 4004 head, and a Peavey 1x15 cab. I seem to have enough power, but I want some more "warmth and roundness" to my sound. I want a warm and round but clean sound. The Sansamp seemed to warm it and round it alittle, but it has too much "tube type drive" to it. I can't seem to get a clean sound using it. Also, I don't like much treble to my sound. Any suggestions? Also, does it make any difference in sound if I hook the Sansamp up "stompbox style" or through the effects loop? Thanks for the info, I am liking it more now!
