hey all, for a while now, i've been thinking of letting go of my DB680, cause to be honest, its too much preamp for me. for the crazy tweaker, its a dream, but these days, i just wanna plug and go. the only thing i really touch on the aggie pre is the 40Hz bass boost, which IMHO, is eerily similar to the boost on my Sadowsky basses. both of which who's tone i completely dig. so, i'm thinking of downsizing to a DB659. how do you guys dig yours? tonally, how do they differ, if any at all?
