Electro Harmonix Hum Debugger

What we say:

The Hum Debugger is like a can of Ronseal: it does exactly what it says on the tin! Put this is in your pedal chain if you are experiencing annoying hum and, as if by the sweep of magic wand, the hum disappears! It is quite something to have a pedal do this simple but incredibly important job.

Be clear, this is not a noise gate or clamp or any of those things that you'd use to tighten up your heavy riffing: this is a box that clears up things like your noisy single coils in your vintage valve amp. It's a great device and more guitarists should use it.
