    Different version preamp tubes do have their own personality and will slightly change the sound. It’s all personal preference but tube rolling can be fun!

    Hi, You would only need to remove the jumper is the line out signal is hot for whatever you are plugging it into. Thanks JT

    Hi There! The thru out on the Alpha DI is 100% unaffected so that would not have the sound of the DI.. on the back there is a line level 1/4” out which does capture the tube tone of the DI. It’s really meant to feed into a power amp but there is an internal jumper that when removed lowers the...
