Warmoth have updated their pickup routing options page with the right Seymour Duncan models that fit each of the 5-string Jazz routings, after I spotted a couple of mistakes and e-mailed them about it: http://www.warmoth.com/bass/options/options_bass_pickups_routing.cfm Thanks to Gregg for his quick response. He said he would also look into Rio Grande specs to include them too. Anyway, I thought it might be useful as a reference, it can get a bit confusing with the different route and pickup sizes available.
