Re: Yngwie's Signature Strat.
Even out of the Malmsteen signature USA Fenders, there are two types.
The first one is the original specs...has a small, vintage 50's headstock. Two point American Standard Trem. DiMarzio HS-3's in the neck and bridge with a Fender Standard Single coil in the middle. 5-way switch.
The second one...has late 60's headstock shape. 6 point vintage Fender Tem. DiMarzio YJM in the neck and middle, HS-3 in the bridge. It has a three way switch, if I recall.
There has also been a Japanese series, where you could get black and cream/vintage white-really yellow. I'm not sure if you can get these anymore.
There are some differences between the sig series and what Yngwie plays. He has said that his personal guitars have a deeper scallop and he uses 'metal' screws to bolt the neck on-tightly. He says this gives a more resonant tone.
