From Seymour Duncan:

The Studio Bass is a studio-grade, classic compressor in a user friendly 4 knob format. Our unique Blend knob and 3 way mini-toggle switch allow you to select the frequency range of the original uncompressed signal as well as infinitely adjust the amount of “wet” versus “dry” signal that is routed to the output. It’s often best to put a compressor at the beginning of your effects chain, but sometimes it can work more efficiently when placed after effects such as an auto wah or envelope filter. You won’t do any damage by putting your effects in the so-called wrong order, so feel free to experiment and find what works best for your sound. Typical applications for the Studio Bass include: • Accentuate picking and single note runs • Increase sustain • Even out all of the notes
