Re: S Prestige and Sustainiac?
I thought that putting the Sustainiac in the middle pickup gives off a lot of feedback and doesn't sustain the notes properly because it is to close to the bridge pickup.
From their website
The space between the bridge pickup and Sustainiac driver is quite small. This creates magnetic crosstalk between driver and bridge pickup, resulting in uncontrolled oscillation. This means that you have to turn the sustainer gain down to stop the resulting oscillation. Sustainer performance suffers so much that you might as well not even have a sustainer.
