i built two of these things a while back. i don't think i've said much about them.
i've had PLENTY of time to get to know them and i'm ready to discuss.....
they aren't an exact clo ne of the 384....or at least from what i can recall......
but, if you have soldering skills, and some time....i'm loving these things.
after a few tweaks i got them super quiet and i'm pretty much using them on every session.
they are simply awesome on the drum buss.
i found them here (follw the link to the DIY lab for details)
http://www.gyraf.dk/anyone else build one of these?
BTW, i've found the DIY community on that message board to be massively unhelpful.....your luck might vary.
