I asked a similiar question to this the other day. I have a passive Jazz bass with Dimarzio Model J pups. It gets a wonderful sound. Low, full, and growly.... I play at church with 9 singers, an acoustic guitar, piano, and drums. My sound guy does not run me through the PA for some reason and I'm afraid the great sound I'm hearing sitting right next to my stack isn't reaching the congregation. Will a preamp, such as the Sansamp Bass Driver DI help focus the sound and carry it to the people in the audience. Will it do similar to what an onboard preamp does.
