The Fernandes Sustainer pu system is awesome! But it needs a lot of space like active pickups it needs space for a 9v battery plus the switch to go someone on the body of the guitar so you can turn it off and on again!

Speak to you local guitar shop. I wouldn't advise doing this yourself unless your feeling very very brave!

Good luck
