Seymour Duncan Liberator Solderless 500K

It takes up about the same space as a 3- or 5-way strat switch, and i spent the same time installing it that i would have installing two new pickups.
You can only get them in 250k and 500k versions with the same shaft length.
And No push-pull or no stacked pots.

But that is the only negatives i can find about this product. And most of them are "theoretical" and wont be an issue for most people anyway.

The pot itself is super high quality and sounds good in action. No scratching out of the box, and no danger of damaging it while soldering, since it has the "breakout circuit board".
The circuit board is also sturdy with a good thickness, and the screw-sockets for pickup wire mounting are very reliable.
I currently have this system in two guitars, and havnet had any issues with loose wires while playing or broken sockets when doing pickup changes/maintenance.

Other than the short installation time i now have on new pickups, i also realized that i didn't have to cut and loose pickup wire every time i wanted to try something new. It feels really good removing a pickup and having the wires in mint condition afterwards.

So if you like to experiment with different pickups once in a while, i can only recommend that you spent the short time required installing this "system".

Okay, so it's actually NOT solderless (thanks SD for the misleading advertising) as you have to join up some of the wires together to make it work. Took me a little while to interpret the instructions and make the thing work, but once I got it, there's nothing wrong with it at all! If you're good with a soldering iron and are prepared to stick it out, I'd probably stay with that, but if you want something a bit quicker and less fixed for later changes, I wouldn't sneeze at trying out one of these!

Il s'agit d'un potentiomètre de volume qui permet, une fois installé, de changer de micro rapidement, car sans soudure!
Attention cependant, cela ne concerne que les câbles provenant du micro lui même. Certaines soudures sont tout de même nécessaires, afin de relier ce potentiomètre au reste de votre électronique! mais il ne faudra les effectuer qu'une seule fois! Un étamage du bout des câbles du micro est quand même préférable.
Attention de bien suivre les instructions fournies dans la notice en fonction de la complexité de votre câblage (nombre de micros, tonalité, type de switch, etc...).
Dans mon cas, je l'ai monté dans une guitare n'ayant qu'un micro bridge et un potentiomètre de volume (celui-ci donc).
Concernant la qualité du potentiomètre, rien à signaler, pas de bruit parasite, le volume varie bien progressivement. Le potentiomètre se tourne bien, ni trop souple, ni trop dur, juste comme il faut.
Donc si comme moi vous aimez changer souvent de micro c'est le truc qu'il vous faut!
