RSP Technologies SATURATOR
The Saturator is a two channel valve distortion unit, and sounds similar to my Culture Vulture but at a fraction of the price. It can do everything from very subtle warming of signals to full-on screaming overdrive. I've used this unit on everything from drums to guitars and even vocals, and it has always worked brilliantly!
There are a few scratches on top and bottom from rack-mounting, but the front panel looks great and everything works as it should. Supplies complete with power transformer.
