Title: Works great
Review: I wish the knob stem was longer so it could be installed with only the stem and knob sticking out of a hole in the mounting location. The knob does come off, but the stem is not long enough for that type of install.

Title: The best of the budget priced
Review: Other than the plastic housing, this is a great unit. The potentiometer has a great feel. Not loose like some loose costing brands. And the RCAs are beefy.
