a Fernandes Decade V-1 w/ sustainer pickup
During many of the Adore shows Billy used a Fernandes Decade Elite guitar, which featured a built-in sustainer system. This guitar has a small toggle switch that turns on the "Sustainer" pickup. In essence its a little bit like having an EBow built into the guitar. He used this heavily on 'Behold! the Nitemare', and 'Bullet with Butterfly Wings'. (thanks to Anders for the correction)
