Bob Rissi, the man who designed the Transonics for Rickenbacker, tells an interesting story. Jimmy had four of these amps, one of which he could not stand in front of due to the horns. This particular amp was left behind and is now at Rissi's house. Rissi seems to think that Jimmy only took one (perhaps two) back to England, and believes Cheap Trick ended up with the others. Also, John Paul Jones had some (exact number unknown), and he may or may not have taken any back to England. Another story circulating is that Page "hated" these amps, but closer to the truth is that he actually hating standing in front of the one speaker box that had the two horns- the sound was too intense. This is the amp that Rissi now owns. There is a great article in Vintage Guitar magazine (https://www.vintageguitar.com/7818/rickenbacker-transonic/), and more information at Rissi's website (Rissonamplifiers.com). Does anyone here have any idea of what one of these amps is worth these days?
