    I've heard some mixed answers on this one. I have the Sansamp Programmable Bass driver DI. Can anyone tell me if the sansamp is TRUE-BYPASS? thanks

    Well it's a preamp, so no it is not.

    I'd like to know too. Especially because the SansAmp BDDI is more of a stompbox than a preamp: if you set effected and uneffected levels the same and switch between them, then there's no significant signal boost.

    I realize the BDDI is not true bypass, but I don't see why it couldn't be.
  6. ANYTHING can be true bypassed... but the sansamp footswitch gives it all away.

    True true bypass involves a mechanical switch - most if not all mechanical footswitches have a solid click when they're stomped on. The sansamp has what's called an actuator for the footswitch. It actuates a small switch mounted on the PCB that in turn controls some switching circuitry. I see no relays on the board, which is just about the only other thing that might be electronically controlled, but still considered true bypass... so no, it's not true.

    While the Sansamp is not true bypass, there's nothing inherent in it being stompbox preamp that prevents such a beast from being true bypass.
