I have a 1964 Rickenbacker 1000-with matching Rickenbacker M8-E amplifier-that I’ve owned since the early 70’s. The previous owner purchased the guitar & amp new. First off, the guitar is beautiful..but it is also functional. I did replace the bridge with a Gibson styled one that allowed better intonation but didn’t interfere with the integrity of the instrument. I also didn’t need to modify the guitar in order to fit the bridge. The instrument sounds great, but doesn’t have a whole lot of tonal choices due to just the one toaster pickup. But it sounds great through my AC30 & plays like a dream. Plus, other guitarist who see the guitar have a fit over it. So, it’s a great piece of vintage design but it also serves as a great rhythm guitar. Love it!!!
