Karl Sandoval : This is something I would really like to make known: I was taught guitar repair in a certain way and I thought, 'This guy (Edward) knows what the hell he's talking about.' (In Eddie's voice) 'You do fretwork this way you do Strobetuning this way you set your nuts this way' and I thought 'This is the way it is'.

Here's a great quote from Karl Sandoval about Eddie's understanding of tuning and using Peterson strobe tuners that appears in Steve Rosen's excellent 'Tonechaser' book:

As I've said earlier, when you hear Eddie doing all these random bar diving licks in between the songs as Dave is talking, THAT is the sound of Eddie diving the bar to keep the guitar in tune. The bold type is the critical partbecause this is what I said earlier in this thread and in many other places over many years.when you hear Eddie diving with the bar, he is in fact also using the bar dive to keep the guitar in tune. Sometimes I’ll bring the bar down before I hit a note and then let it up. See, I rest the palm of my hand on the bridge, so If I use a standard vibrato, I sound like a warped record. I also set the vibrato bar so I can only bring it down you can’t pull back on it. I have extra-wide notches in the nut, and string trees for only the high E and B strings. A lot of people drill the machine holes off center, and the strings get caught up. For one, some manufacturers don’t keep in mind that the distance from the bridge to the machine heads has got to be straight line so the string windings won’t get caught anywhere. Guitar Player (Jas Obrecht): How do you keep tuned while using a standard vibrato?ĮVH: It’s a combination of a lot of things. You can’t just grab it and jerk the thing and expect it to stay in tune. The vibrato is actually like another instrument. Like if you bring the bar down, the G and B strings always go sharp when you let it back, so before you hit a barre chord you have to stretch those strings back with a real quick little jerk. I have special tricks for keeping it in tune, but it still goes out. It calls for a totally different technique. I really don’t have any special chops with it. I don’t really use it for freak-out effects I use it to enhance a little more feeling. GP: What are your views on using a vibrato bar?ĮVH: It’s more of a feeling as opposed to an effect. In the unedited version of the April 1980 Guitar Player magazine interview with Jas Obrecht, Eddie confirms what I’ve been saying for many years about part of his method of keeping the standard Fender vibrato system in tune:
