Essentially I want a circuit that can transform my passive pickups to actives. I have searched around on google a bit, and found one circuit that uses a single FET. It looks good, but I want to know what other folks have tried. I am trying to get extremely high gain output, for playing metal, etc. Essentially what I want is something like the EMG afterburner, but I want to be able to customize it and of course have the fun of building it myself.

Any ideas? Has anyone done something similar?

Do you want an external box or something to fit inside your guitar ?

I use a Zoom 707 effects pedal for my sounds.
It was about £150 but worth every penny for the massive amount of different sounds it can create.

If you just want valve type overdrive metal sound then a soft limiter is a good circuit. Or just buy in one of the many valve type distortion boxes.

Thank you all! Extremely helpful.

I am going to attempt to build this:

and wire it up to my EMG HZ (passive) to attempt to get the EMG 81 sound. I realize that the EMG 81s are wound with thicker wire and less turns, so they get lower noise, but I am going to see what happens. Perhaps a boss ns2 will cut down the noise.

I might also attempt to build this:

And I will read through this thread and pull any useful info out:

I will report back on my progress.

Cheers!
