I saw that second guitar it NAMM in '94 or 95 I think. Some German guy was selling it.
You can take the pickups out easily, and configure them in different ways to change the sound, in addition to being able to move them in the scale length. You could change those tubes with others as well
It was'nt the most comfortable thing to play, but it was interesting.
It was expensive too. I think it was like 5000 US then, if I recall correctly. I could be mistaken, but I remember it being costly.
What a trip to see that thing again!
