The Tech 21 SansAmp Para Driver DI was designed for bassists who are looking for a warm, all-analog "rig-in-a-box" that gives you 12dB of boost or cut, a semi-parametric EQ for precision tonal shaping, and three separate channels for a variety of sounds. This DI is, in fact, much more than just a DI - it gives you organic warmth and eliminates harshness from pickups for fantastic analog tone.
