Interesting find last week, came across this early 60's Guyatone GP-24 sound hole pickup on Craigslist shortly after it was posted, immediately arranged a time to go check it out. It requires no modding to install, it clamps into place with a clip on one side and two little pivoting spider arms on the other, and it's actually very sturdy, doesn't move around at all while playing. It has its own volume/tone controls and an input jack. Sounds fantastic, very clear with lots of tone control, I'll try and get around to recording a tone demo some time this week, I'm currently running it through my MESA Lonestar's clean channel.
Thing looks bizarre, never seen anything like it.
