Chicken head volume dial, input jack, output jack... Simple
It's cheap. Makes you realize that if you're spending $1700 on a custom shop guitar, you're an ass if you skimp on amps and amp accessories?
It's really a piece of garbage. It worked phenomenally for about a week, and then one day it just started sucking the tone out of my amp, and for some reason the presence and reverb wasn't working right (I had just gotten them fixed). If you don't have a serial FX loop than it won't work, and for some reason I couldn't get my chorus pedal to work with it in the loop, but the chorus sounded fine in the front. The label on the box is cheap, the ink literally got smudged. Not a true power attenuator, can't be used between the head and cab.
What reliability?
