Overall, I'm very happy with this product. It does provide a wider and blended (you control how much) tone variation over the basic 5-position switch. A minor complaint is that - to me - the blender knob works backward from the master volume and tone. That is, if I want more tone or volume, the knobs are turned in the same direction. I would think "blend" would work the same, but it's opposite - full on is zero blend, knob turned off is full blend. Also, I ordered a Univeral blender and was following the wiring diagram until I realized my connector had 14 pins vice the 10 on the diagram. A double check of the box revealed I received the Gen 2 version which has the the 14 pin connector. The instructions say "Easy but not Instant". I'd call it "Do-able but fiddly and plan on installing it twice before you get ot right".
