FIRST OF ALL: Before you order, MEASURE your guitar cavity / current pots. Product dimensions are there for a reason. Some other reviews mention them being big, and indeed "measure before you order". Absolutely do this!
SECONDLY: Some review mentioned "no schematics which contacts belong to which contacts".
This is true, but on the other hand, it's quite standard.
At the bottom of the pot (at the frond, on the circuit board) you see one vertical row with "1, C1, 2" and a second row with "3, C2, 4".
When it's in PUSH position, it's C1+2 and C2+4 and on PULL, C1+1 and C2+3.
Otherwise there's obviously also the possibility to use a multimeter to measure which contact belongs to which one (IMO a tool you should have when working on electronics, including guitar electronics/soldering).
Now for my ACTUAL review:
I like these more than my old pots (Gibson 500K pots, without p/p). The "vintage audio taper" gives nicer control over volume/tone IMO (at least nicer control than logarithmic pots, like my old ones).
They appear sturdy (I did accidentally pull out one knob when trying to remove pot knob, which was attached pretty tight, but I could easily push it back in). Push/pull works great and feels sturdy too (the knob I pulled out was done with quite a lot of force because the knob was attached thát tightly).
I saw some review where pot died after a month. I didn't have it that long but I can't imagine that suddenly happening. If it does I'll see if I can edit this review but I don't expect that :)
