Did NOT notice the Sustainiac! Just a note... One of my customs, the "Gaudy Paul," had a Fernandes Sustainer (which is a licensed version of the Sustainiac). (I had to sell this one and it was bought by Space Cowboy here who, unfortunately, has passed away which means I have no idea what happened to the guitar!)
Here's what it looked like originally:
But it only kept the Sustainer for a short time because I was restricted to using one of Fernandes' pickups and for some other reasons I didn't like. So, out it went and here was the final result:
I still want a Sustainiac, but the version I wanted to get (Model C) is their clip-on model which can obviously be used on multiple guitars! Unfortunately, it's been out-of-stock for a long time! The Model C Sustainiac
In any event, it's a good thing you're getting a real Sustainiac!
