After more than a decade selling PUTW pickups, the #27 is still my favorite. I know, PUTW recommends dual-sourcing, either with the #54 or the Dynamic Duo, both excellent pickups in their own right. But with all the PUTW pickups I've installed over the years, I always seem to get the best tone with this guy.
It's super-easy to install, easier than just about any other soundboard pickup with the possible exception of the B-Band AST 1470. As with all PUTW pickups, you absolutely need a good preamp close to the guitar, so keep that in mind when ordering.
