Is it the materials, or they way it's assembled? Maybe the skill of the luthier? The necks are 3 piece maple, neck-through. Nothing unique there. Flame or quilt maple body wings. Ebony fingerboard. Plenty of those in bassland. I know the finish on the fingerboard has to play a big part, but these basses just sing and sustain forever. And the low B on the Pentabuzz is easily the best I've heard on a fretless - on a 34 inch scale. So does anybody know what the magic fairy dust is that they use in the Pedulla shop?
