One guitar I play is a 1997/98 Fender Telecaster Thinline CIJ, from the Fuji-gen plant, with a rosewood bridge and a Shadow PU placed inside the bridge itself under the bridge nut.
There are no other PUs on the guitar, on which I have mounted medium light steel strings in place of the nylon strings originally in place.
I have also placed the thin metal PU bar slightly lower and snug to the rosewood for better resonance.
I feel the need for an even better PU since I run the guitar through my EHX FX.
(The present one on the guitar was factory mounted in Japan).

My question is:
Which Shadow/Piezo PU is the best on the market today?
