||Active vs Passive|
To start things off..... hehehehe.
Just quickly to get things rolling..and I'v got to go to college in 3 mins..
Active vs Passive, pro's and con's, this should get some blood flowing...
Pro-Sounds Better, mine do anyway, hehehe.
Pro-More gain available.
Con-Expensive to manufacture.
Con-Can be limiting.

[his active pickups fail to suck]
Kewl. Did you hear about how EMG had to
bandwidth limit some of theirs in the late
1980's because their extended high frequency
response caused a lot of aliasing artifacts
when run through digital delay units?
Out of curiosity, which opamps do you use?

I limit my bandwidth for this very reason... and if I told you what opamp I use I would have to have you decommissioned, so to speak... hehe.
I dont know if you've ever heard my stuff but they are definitely not like EMG's...

I'm sort of curious about what you do to filter off
the inaudible high frequency stuff. This is not
the same as asking what you do in the pass band to
achieve your unique sound.
As for EMG's, I thought they needed 27VDC across
them to sound reasonable to me, but ears aren't
remotely what they once were. Even so, it was
obvious they were using a middling opamp.

I would love to tell you but I can't.. trade secret stuff. As for the voltage I agree, EMG do need a good kick in the backside to get them going, even then they are limited due to their inherent design. My design though still works just as good at 4.5V than past 27V, although you don't need to take it to that extreme.

Just to add to that without going into specifics, lets just say its got nothing to do with the opamp but more what you offer the opamp to process that counts...ahhh, said to much... I will self destruct in 5 secs.....

Anybody'd think you were slightly biased!
Don't tell us you actually make active pickups (tehe)
In all seriousness although not my favourites they do have they place, doorstops!!!
To those who don't know Tony makes some of the finest active pickups created, pity they don't get wider distribution and/or publicity.
