I'm planning on buying a new DI box in the near future, but I want one that can add a bit of "grind" to my tone. I fell in love with the sound clips for the Sansamp Bass Driver DI, but I've also been recommended the MXR M-80. Whichever unit I end up with will be used for both recording and for live performances, and aside from supplying my live sound/recorded sound to the board they will be used to dial in some grit, grind, nastiness, etc. I'm not looking for full on distortion, just some......... ugliness. Which would you recommend? Why do you prefer one over the other? Thanks in advance.
