I have been trying to get a preamp from G & L for more than a year. I have been going through a local G & L dealer. I have actually heard him dealing with the G & L rep several times. I bought the bass with a non-functional preamp, so I don't have any problems with the seller or anything like that, just an unresponsive manufacturer. Does anybody know of a similar sounding preamp that is compatible with the Tribby?
