I am considering experimenting with a blender for my Strat neck-bridge pickups.
Whilst I use my volume control, the only time I use the tone control is on my Tele's bridge PU. Should be fun, considering I've had a positive experience using a toggle switch to activate my neck pickup 100% into any of the PU settings.
YMMV of course.

Blender wiring allows you to get additional useful sounds from a Strat without adding complexity or changing the look. There are no additional controls involved, no mini switches or push/pull pots. The system is simple and intuitive.
Vintage Strats have a volume control and two tone controls. One tone control is for the neck pickup and the other is for the middle pickup, there is no tone for the bridge pickup. The original thinking was that a player would have three tones from which to choose by using the 3-way switch - two were rhythm tones and the third was the lead tone (Fender never used a 5-way switch during the pre-CBS or CBS eras). Consequently, the two rhythm pickups were each given a tone control so their respective tones could be preset, and the player could easily switch between them. It wasn't felt that the bridge (lead) pickup would need a tone control. This "preset rhythm tones" approach was pervasive at Fender in the early '50s, the Nocasters and early Teles had similar thinking behind their configurations, as did the Esquires.
Many players like this setup of multiple tone controls (many are simply used to it after all these years), but many other players prefer a single "master" tone control. Additionally, lots of players like the idea of a tone control for the bridge pickup as it's the one most often pointed to as being overly bright. Turning the middle control into a master tone control is easily done, but that leaves a pot that's not doing anything, so using this third pot as a blender control to gain additional tonal flexibility is a no-brainer.
The blender is simply a control that allows you to blend (mix) the neck pickup or the bridge pickup into the signal. If the 5-way is in the neck position, it blends in the bridge pickup. If the 5-way is in the bridge position it blends in the neck pickup. Add as much or as little as you want. You can add just a little of the neck pickup to warm up the bridge pickup, for example. And if the 5-way is in either the 2 or 4 position, you can get all three pickups on (which actually is a pretty useful tone too).
Blender pots are 250K pots like the other two, and in fact you can wire a regular pot as a blender control, but it will allow bleed-through when turned "off" so you can never get it completely out of the circuit (in other words, you can never have the neck or bridge pickups completely by themselves, you'll always have a little of the "off" pickup bleeding into the mix). We use special pots that we have manufactured by CTS for blenders, these allow no bleed-through and are completely removed from the circuit when turned "off" (fully CW), similar to the way a true bypass switch completely removes a pedal from a circuit.
So there you have it. If you must have two tone controls then you can't have a blender; if you don't want two tone controls then the blender is a useful thing to do with that third control. More than 50% of the assemblies we've sold to date have had blender wiring, it's our most popular wiring option.
