Doe anybody have any information on the Rickenbacker R75B? I picked one up in trade and I can't find any info other than it was probably produced in the '80s. It has surprisingly great tone. Thanks.
I had the same problem which I thought was a ground issue because it would reduce if I touched the Bass Buddy case. I found an 18V power supply from an old laptop and the problem went away. The 20V power supply that comes with the Bass Buddy is crap.
