I just got done modding my Tribby L2K with a 3-way switch to go parallel - SC insides - SC with bass boost. Also added some Superalloys and this baby is singing. All this got me looking at my wiring diagrams and it is time for an update. Same link as before. If you are modding a Tribute you do not want to use the old document because of the shielding. The old mod document could have problems with the Tribute grounding / shielding that is different and an improvment over the older US ones. The new document can be applied to any generation of G&L L2K bass. The Tributes have great shielding in them and the green wires on the pickups are tied to the cavity and to the pickup magnets. So I have changed the wiring mods so they do not move the green wires away from ground. The coil switching results will be just like the old document and as stated can be used with any generation of G&L.
