TD-100 Preamp & Direct Box FAQ

Q. I don't hear anything change when I turn the impedance dial, is there something wrong?

A. Some high output instruments are not affected by input impedance. New digital keyboards and active pickups are usually unaffected by the impedance control.

Q. Does the direct output pass through the tube stage?

A. No, the direct out is just a loop from the input. However, the impedance control effects the instrument itself so any changes to the impedance will affect the sound you hear in your amp.
