ok, so i recently took apart my mexican electron blue SSH Fender Stratocaster (completely) , im planning to put it back together with almost everything changed, one of those changes being an EMG 81 Active in the bridge position. Now, even though i am probably gonna have a professional install the pickup, could someone give me a basic idea as to how installing an active pickup differs from a passive, and any additional parts i would need to get to install, i hear that you need to get different pots. If so what kind of pots are needed when installing an active. thanks for youranswere
