    Hey guys,

    I've been working on an audio effects box (kinda like an effect pedal). Right now I need an amplifier with a gain controlled by a voltage. I've looked around the internet but haven't been able to find anything like it. Any ideas? (also, using only BJTs or op-amps would be helpful as that's mostly what I've got sitting around here)

    Thanks

    OK, thanks. That looks like it'll work great.
