So I am replacing the EMG 81 that came in my RR24M with a Seymour Duncan and I was wondering if anyone has played both the TB-4 and TB-5?

The site says the TB-5 is a PAF on steriods, but I don't really understand what they mean?

SO if anyone has played both please chime in and give me you opinions.
