Tux789,
The 707 does indeed sound like a mix between an 81 & 85.
I got 2 prototype 707's from my friend Dino Cazares (ex-Fear Factory) who was actually the one who first had EMG make the first 7 string pups. I had them put in my custom shop Carvin DC727 and to sum it up, on the low strings, it sounds like an 85 and on the high strings, it sounds like an 81 but these pups have even MORE gain (Distortion) than either the 81 or 85.
I don't know if you'll like 'em since they sound too much like an 81 & 85 and I remember how much of a nonconformist you are n' all !!! J/K
