On Thursday my son took the Senator to a jazz gig at a gallery opening and I got a chance to hear it from the audience in a band context.
Strung with TI Jazz Flats and played through a GK MB150 combo, it sounded very "acoustic", like halfway between electric bass and upright. More open and slightly punchier than a "Beatle bass".
My son commented that he would like to raise the action on the E string side, but otherwise he loved it.
4.4lbs., by the way. It's the Weightless Wonder.
