hey all, after being seduced by the Sadowsky side, i havent picked up my Elrick in a long while. and yet, recently i've been getting back to Betsy, remembering how great it played. still, i do want to do something about its sound. the bass itself is Classic Singlecut 5, swamp ash body, maple neck thru, macassar ebony board, Bart humcancelling J's, Bart "NTMB-918F" 3 band w/ 3 notch midrange selector switch. while, i know that the aguilar's freq's are spec'd at 40Hz for the bass, 6.5kHz for the treb, cant find the same freq specs on the Bart site for my preamp. anyone know them? and any real tonal differences btwn the two i should take note of?
