I am interested in a DI that will go between the head and the cab. Which ones do this? I want the pre from my SVT going through to the FOH. I use a passive bass (P-Bass) 100% of the time. I am also thinking about a mic for the rig, but this DI option of using the SVT pre seems far better than just a bass into a box into the SE hands! So...Radial JDI? (Passive or Active?), Countryman? Do these do this? I am a newbie to the DI box scene. HELP!
