Hello, I run a Sansamp RBI into an Ampeg SVT-VR head, and lately I've been using the Boss Overdrive ODB-3 to add some roughness to my sound. I'm still not quite able to get the sound I'm looking for - something similar to Circa Survive. Does anyone know whether the purchase of a Tech 21 VT Bass would be worth adding to my rig? I finally heard about it today. Thank you.
