Re: Anyone else hear any tonally similarities between the 81 and the JB?
Its possible. Remember the EMG is actually a fairly mid to low output pup in terms of its magnet and coil windings. I think it also uses an Alnico 5 magnet like the JB. What gives it the "umph" is the pre-amp/9 volt battery. So in theory its like having a moderate passive pick up in your guitar (like a JB), and using a pick up booster, OD pedal, etc., to boost the signal and slam your pre-amp to give that push. Of course it won't sound exactly the same, but I think theoretically you're doing the same thing. What an EMG won't sound like is a high output passive pup with a big magnet and windings, i.e. Distortion, Invader etc.
