I'm posting this here since it is more of a "pre-amp / power-amp" question then an effects question... I'm looking at getting the new programable Sansamp to give me a little more variety of tones to choose from. Do you guys see any problems running it and my bass directly into the effects return of my Ashdown 500 EVO II, leaving the effects send unplugged, therefore effectively by-passing the head's preamp? I would then like to leave one of my basses plugged directly into the head's pre-amp, and the other into the Sansamp so I would have everything ready to go with little screwing around between songs... Would this work? Comments? Suggestions?
