LOL this is from 2004? I came across it and saw that you had a question and, incidentally, I was just coming across the answer so here it is (just in case)...
On the EMG Powering / Tips and Tricks document it says "Headroom is defined as the ability of the pickups to deliver a clean, undistorted waveform."
I'm looking into upgrading my Spector (incidentally like yours) from 9V to 18V. Hoping this annoying, distorted 'buzz' that I get will go away!
Fingers crossed! Will keep you all updated
