An inexpensive option


from RVA

Comments about Nady HE-1 Hum Eliminator:

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 pedal...no hum. It's a great inexpensive option compared to some of the others.
