Hey, Stephen!
When I was checking to make sure everything works, I ran the front panel DI, rear panel full range, high out and low outs into my Roland VS2000CD unit simultaneously to make sure everything was A-OK. The routing flexibility of this unit is awesome, like a Swiss Army knife. And the front panel DI can be either post- or pre-EQ (in the latter position it's the straight sound from your bass w/o any coloration or frequency boost).
And if you periodically exercise all the jacks per several threads here in the club, the unit is dead quiet. Trust me, I'm only selling this unit out of necessity!
