no I use the same gold plated Planet Waves guitar cable on all my guitars active or not, I've never heard of stereo guitar cables though.
Yes. Call music places and ask them if you don't believe me
You can put new pickups on pretty much any solid bodied guitar.
Most pickups are passive but over the last several years active pickups (powered by batteries) have become popular with some players (like David Gilmour). EMG pickups are some of the more popular active pickups.
The KH-602 has active pickups but the KH-202 has passive pickups. It is possible to convert to active - either EMGs or Seymour Duncan but you would have to find somewhere to put the batteries.
you can put them on any guitar from walmart guitars to any real guitar like your RR5. It'll cost a bit extra to re-wire the guitar to fit the EMGs in it as they take out all the old electronics but if you really want to go active by all means. Once they're in its the easiest thing in the world to switch them to other active pickups.
Lundgren guitar pickups was created in 1990.
humbucker (big ones like on les pauls) single coil two types of pickups as in "class" are passive and active
nope but if your asking this because having problems hopefully its the batteries lol
Active pickups have 9 or 18 volt battery passive has no battery
If you put it over the strings or pickups it will have a bigger effect on an electric guitar, on an acoustic it will deaden the sound if applied to the sound board.
There are many sources to get guitar pickups online. Companies like Guitarfetish, MusiciansFriend, TVJones, and EMGPickups are just a few of the online companies that sell guitar pickups.
