I am selling my Tech 21 Sansamp RBI, it is the rackmount version of the Sansamp Bass driver DI. most people know the specs on these so let me know if you have any questions. I used this for some recording, it is in "like new" condition and makes a great preamp. I am asking $225 for it and that will include shipping to the lower 48 US states. I can get pictures if you want them.
