The Red Sun FX Pictureboost may seem like a simple one knob boost, but in fact it has internal DIP switch that turns it from a boost to a buffer. It is a transparent, MOSFET based boost, that will give you anywhere from 3db to 35db boost. The boost knob is designed to require a bit more effort than usual when to turn, that is to prevent accidental movement of it during live performances. The Red Sun FX Pictureboost is made by hand in Germany.
