Got my SVT 3 pro in today. Hooked up to the SVT 610 hlf cab and Birdsong bass. Wow!! This is loud and so much more sustain than I'm used to. In a room with terrazzo floors, a wall of windows, stuff hangin on the walls, this thing is rattling everything. I hope it's the room and not the cab. I'm Lovin the sound all but the Low open E. all other open and every fretted strings sound nice with a fat centered pitch. The open E Has a very dirty sound with the harmonics, mainly the 3rd taking over. I can't seem to dial in a good fat sound on the open E. I'm thinking its got to be the room.... Hoping anyway!!!
