BPB Saturator is very nice sounding, and super easy to dial in. I don't personally have a lot of experience with analog hardware, but just from how it sounds, the tube is fantastic to my ears on loads of material. I like to dial it in creatively after some compression or even heavy limiting to give the sound some very nice crunch, it doesn't break up quickly at all. I'm also particularly in love with the high pass filter, there's something "magic" about how it operates, possibly linear phase because it doesn't cause huge spikes in peak level. Absolutely worth it for the price tag;).
