Hello,
I've been searching the net for a good low frequency preamplifier, and have come up short. I was wondering if there was any the users of this site could recommend?
I'm interested in the range of 2-200Hz, most preamps are only really good down to 100Hz, 10Hz at a push!
I really like this preamp, having used it before, but as you'll see from the frequency response the roll off is pretty bad below 100Hz.

Ideally, I'd like something with little roll off at very low frequencies (around 2Hz), lower power requirements than the one posted (preferably around 3V), and fairly simplistic to change the gain.
Cheers
