Whats the difference between active and passive EMGs?

never tried the HZs before.. only know the hzs were used on lower end products ... to give the EMG look.

the active pickups are great... 3000 playing hrs if im not wrong... just get a good alkaline battery will last about a year... cool stuff. not hard to change battery.. just open rear body cavity ... simple job.
 
Hz is short for High Z (impedence), which are passive pickups. You did ask the question bout the difference between the two anyway.

Passive pickups are basic. Magnet withs coils of wire. Basic physics here, strings cut magnetic flux, produce electric current. Output of passive pickups are high impedence, so running through long cables will result in signal loss, esp in the treble freqs.

Basically active pickups use weaker magnets, hence also weaker string pull, have a low internal signal, which gets boosted by a built in active (think battery) preamp. The output signal is low impedence, so you can use long cables without having to worry bout signal loss. Quite simply, they are weak passive pickups boosted by a preamp.

Tonal wise, it's always a personal preference issue. Personally, I'm not a fan of active pickups for guitars. Good for clear cleans, but tend to sound fuzzy and synthetic on higher gain applications.

For installing batteries, as long as your control cavity has sufficient space. Not if, you could always find a trustworthy guitar tech to route a hole to install a battery box, which will also be easier to gain access to the battery from the control cavity.

cool ... do basses have pickups ? wads a humbucker anyway ? i like c it onli on gibson or epiphone guitars ...

lol of cos, unless it's an acoustic bass. A humbucker is a pickup with 2 coils wired in opposing polarity. Cancelling out hum, hence the name humbucker. Humbuckers are very common place, even in basses.

Read this. It applies to all electric guitars and basses:
