In the March '92 issues of Bass Player, it's reported that he "currently tours with several 80's Fender Jazz Basses and a Tobias 5-string, all with Bartolini 94J quadrophonic pickups" and that he's "really looking forward to seeing the new Epiphone John Alderte Signature Bass; it will incorporate my ideas of what a bass should be: a Precision body with a Jazz neck, Bartolini 94Js, a Gotoh bridge, and a graphite nut'".
I personally don't recall ever seeing any such signature bass on the market, however. Blame grunge if you must.
