Search: little bear rat pedal, on ebay. They make a three in one (with a LM308AN op amp, as in the originals) called R.ATTACK, you can select vintage/turbo/dirty mode with a selector switch. The turbo mode is a bit gainier as it uses leds for clipping. Very good build for such a low price.
I was gonna mention this but I know of one guy who had his randomly die on him. So I avoided saying anything until I could further confirm their reliability.
