When used with the specially designed Humbuster™ audio outputs of Fractal Audio Systems products, Humbuster™ cables reduce the hum caused by ground loops. Use a Humbuster Cable whenever possible between the 1/4" outputs of your Axe-Fx III, FM9, FM3 or AM4  and devices like preamps, power amps, guitar amplifiers, etc. 

These high quality cables have a nice flexible feel, with endplugs heat-shrinked for maximum durability. The heatshrink is color-coded, so you can easily find the black end to connect to the Humbuster output of your Fractal product and the blue end for your amp or other device.
