I installed the VFS1 pickups and the Haeussel ST Classic's a while ago, and I love the setup! The VFS1 is just such a nice/smooth/fuller sound, and the classics have some really nice quack to them. I'm not sure I've heard it quite like that out of my vintage Tokais with the E series pickups. Definitely more Knopfler sounding. I have not plugged in alot lately, so I'll have to do some comparing. I mainly play on my couch unplugged anymore, trying to learn from utube videos, such as yours. Anyways, I just wanted to say thanks. The install was easy. I got it right the first time.
Played throught a ceriatone overtone special amp, in tapped position, they sounds great.... Much better than some "highly named" pick ups... In fully position you got the best of FS-1 voice... Two different pickups into once.. I got even f500t pick ups.. and I can really say that the standard quality is very very high!
