So ive been doing a bit of research, and I have come across my guitar playing dream pickup. Sustainiac Stealth Plus pickups. Using an external power source (battery in this case) you can hold a not for as long as you desire or untill the battery runs dry. however. I have not been able to find a dealer of these amazing pickups. does anybody know of a site that carries them? and also, if anybody here has them, would you reccomend them?
