I have a pair of 59 Clones in a semi-hollow. They are very clear and bell-like.
The guitar they are in is rather bright, so at first I wasn't sure if I liked them. But they've grown on me in a big way, I especially like that they retain clarity when rolling the volume and tone knobs back. I believe they are A4 magnets IIRC
Same. Installed a set in my semi-hollow a few years ago. The clarity and articulation is fantastic.I can verify this... my ES333 came with 59 clones already on-board, and they were a huge pleasant surprise
