these look awesome. anyone have any experience with them. relatively high prices. the insertable eq modules are an EXCELLENT idea, if they develop different ones to get different bass sounds. i always wondered if you could somehow have like.. interchangeable pickups. i know spalt guitars made the vViper bass... but i mean all out place a musicman pup here, j there. itd have to be like plug and play.. some special adaptors. but anyway, any one of any brubakers used ?
