Hey guys, can I put put the fernandes sustainer neck pickup alone on my luke without installing the system, or I need to put the hole kit so I could get the effect?
Well, yeah... the Sustainer does one thing... it sustains notes. It's up to the player to do something creative with it.
For what it's worth, if anyone is considering a sustainer unit, i'd strongly recommend the Sustainiac Stealth and Stealth Plus. Their on-board preamp is much more compact than the huge Fernandes board, and can be installed in more guitars with less modification.
Allan Hoover is also extremely helpful and can provide you with customized installation instructions for your guitar's specific pickup and switching configuration.
