I bought this as part of a pickup swap / rewiring job on my Squier Mustang HH. I installed it as a tone pot and wired the push-pull switch for splitting the bridge humbucker (neck position is a P90). The PCB makes it really easy to wire the P/P. There was also some space between the PCB and the pot itself to tuck in my capacitor and retain the original profile. Do beware that it is a full-sized pot and quite bulky, more so because of the P/P. Be careful and measure your guitar cavity before buying. The Mustang control cavity was a realy tight fit and I had to modify the part a bit by bending the two prongs at the top. I also routed the cables around the pot as there was no space behind/underneath it. The control plate on the Mustang is relatively thin sheet metal and the pot sticks up a bit above the surface, but that doesn't really bother me. Luckily I had no issues with the thread diameter and it dropped right into the control plate opening - no wobble, no need to enlarge the opening. For the knob I used a metal screwable one that has a smooth inside surface and is made for 6mm shaft. If you want to get a knurled knob or re-use your old knob, check your measurements and make sure it has the correct number of splines for the US standard.
Overall I am really satisfied with my purchase, even though I had some minor issues with the fitment. The pot functions well and I am happy with the tone responce I get from the vintage taper in conjunction with a 47nF capacitor. It rotates smoothly and doesn't scratch. Push-pull works as expected. As with any guitar mod, my advice is to measure carefully and be prepared to adjust some things if necessary.
