Installed in an Inspired by Gibson Epiphone 335. The solderless connection for the pickups makes a real difference in a semi-hollow. The installation went as well as it could, considering that you have to pass the whole wiring either via the f hole or the treble pickup cavity. Sound-wise, that made real difference with the original wiring, the pickups sounded more open, and I was able to tune in all the nuances I wanted.
It might be a bit on the expensive side, but I have no regret. Great added value.
