  • An inexpensive option

    As reviewed by Mike on 8/14/2008

    I bought the Nady HE-1 because I was having a problem with cycle hum with a reverb pedal. The HE-1 is a passive (no batteries!!) box to add to your signal chain. It works perfectly; I had my doubts but when I added it right behind the offending hum. It's a great inexpensive option compared to some of the others.
