Alrighty, so I have a custom order placed for a guitar but that won't be here till early next year. In the mean time I want to build a HB-4 bass. I've looked around on line and Hoff bass pick ups run to about $120 each, I read a thread where a guy asked Seymore Duncan and they suggested he run guitar mini humbuckers and he reckoned that the vintage SD mini humbuckers sounded great. Anyone else built a HB-4 and replaced the pick ups?
