Tube preamp by Fred Nachbaur

This is a tube preamp by Fred Nachbaur. Visit his page at for more info.

Make sure you know what you're doing since this pedal uses high voltages. You could get hurt or blow something up so be careful.

We're sad to announce that we just received notice that Fred Nachbaur has passed away. You will be remembered Fred.
