The fretted is ash body, mango top, and morado fingerboard. The fretless is alder body, redwood top, and ebony unlined fingerboard. Both will have Pete's "estate" finish which is a poly/oil thin satin finish.
Supe, I used to play nothing but 5-string. I got back into 4 some months back and like it a lot but they are two different instruments. 5-string gives you some serious advantages, especially if you're reading charts or are tired at the end of a long night as you have more notes available up the neck without having to move your hand.

He is a great guy and a one-man operation. Wood comes in, basses go out. He specs the pickups and strings and uses East preamps. No cnc, no automation.
