Check the listing for details. Demonfx G String Filtration II Noise Reduction for Effects Loop/Signal Chains. Condition: New. Listed at 49.53 USD. Demonfx G String Filtration II Noise Reduction This is the very latest offering from Demonfx. Based and inspired by the original G Series, this is Demon's take on a very useful addition to your signal path. This is NOT just an in and out noise gate, but rather offers a pathway where you can take the noise out of a gain section (for example) while leaving out your modulation section. Many ways to place it, but again do make sure this unit is for you and you do have a robust effects chain to work with. Some pathway examples are noted here, and I am sure you can view some of the videos of the original ISP unit for more information.Well worth the price.
