From the TV Jones website:
The Power'Tron Plus was born out of our desire to create a Filter'Tron-sized pickup with a strong midrange presence and high output, while still retaining the famous sparkle and bass-note clarity of our TV Classic.
At the heart of the Power'Tron Plus are two extra-tall bobbins, allowing for more winds of standard-gauge wire. Single treble notesare reproduced with a full, midrange fatness, while bass notes twang out deep and clear.Overall, the tone is remarkably close to a fifties PAF humbucker, blended with a zing and twang that is all Gretsch®.
So, you ask, how is the Power'Tron Plus bridge model different from the TV Classic Plus? Well, the Power'Tron has a tone that is fat and full — the result of tall coils wound with standard wire. The TV Classic Plus is more like a vintage Filter'Tron™ pickup with extra-attitude — this due to more turns of thinner wire on a short bobbin.
