I need a preamp to start to use to record bass with my hip-hop and R&B beats.. I'd like something with tweaking capabilities so I can alter the sound of the bass as needed for different songs.. The Sansamp I know has a good rep. but can you get different sounding tones out of it? Is the POD worth the $350? And the Art Tube's catalog description states that it can be used for vocals, bass, guitar... I imagine it wouldnt be as good as the sansamp or Pod specifically for basses..
