First time using an active pickup. Installation should be very easy, but beware of "non standard" parts, like a smaller pickguard or tube/stave jack connector. Even then, I was able to install it without too much problems, and everything was working perfectly.
The sound is a little underwhelming, and I would recommend you look up a tone comparison to see if this is really what you are looking for, but you can't really go wrong for this price. In the end, while the tone is not what I expected from it, it is still a very good pickup.
