This is one of the top saturators out there for my purposes. I prefer its tape saturation to the many other commercial tape plugins I own (Slate, Softube, ToneBoosters, U-he etc.). The tube portion can be very effective to increase the "bite" of a track. The controls are laid out nicely and you can dial in a sound quickly. You can go from subtle to over-the-top with both tape and tube. I honestly didn't expect a free plugin to be this competitive and was pleasantly surprised. I will be checking out BPB's Dirty Filter now.
