I have a Rogue 5 string on a four string neck. Takes a little getting use to the smaller string spacing. This was a custom guitar that a friend won in a drawing. It's got all the goodies: Quilted ash with purple heartwood, Ebony fretboard with the leds, and an Alder body this beauty takes 5 9 volt batteries. I run it through an F-1X to a Carvin 1000 into 2 Agular GS112's. With GHS bommers it's fat and deep. My other bass is a Charvel 4 string red lacquer acoustic with black flat wounds. I gig with friends that like Stevie Ray, Kenny Wayne Shepard, and Robin Ford and all the blues with Tommy Shannon. I love the sound of those Agular GS112's. Would any body please tell me about the Alembic Superfilter, would that make it go even deeper? Austin, Texas Ya'll.
