I bought this a while back and applied it today on a Harley Benton TE52, on which I did the 4-way-switch mod. After shielding the pickguard, I can only hear a low 60 cycle hum when using only the single coils. Did the job exceptionally. Covered almost the entire standard Telecaster pickguard, not sure it would cover eg a 72 custom Tele or a Strat pickguard.
It came wrinkly but you can fix that by forcing a plastic card on it when applying.
