1uF - non-polarized or electrolytic?

[dachshund]

Noob alert...
I recently built something with 1uF caps in the signal chain, but didn't specify electrolytic with the usual symbols.
Since we can get non-polarized at this value, is it generally better to use non-polarized, or does it matter? (provided I figure out polarity).
Smallbear has those blue box-shaped 1u's these days, so I wondered.
I think this was the EA tremolo, as an example. I used the blue non-polarized ones, and it sounds fine.
Thanks in advance.

Being able to "get" nonpolarized at a given capacitance value doesn't mean you can get them at the minimum acceptable voltage rating, which in turn means you may not be able to get them in a size/package that is compatible with a PCB layout.   Electrolytics are going to be, or can be, MUCH smaller, with longer leads.  I suppose it depends on the board and enclosure, but sometimes whatever possible sonic improvement might hypothetically exist by using nonpolarized caps is offset by the manner in which the larger footprint and taller profile of nonpolarized caps oblige you to arrange your panel mounting of controls and wire routing.  Sometimes, a smaller, lower profile component gives you more latitude in running the wiring and controls the way they ought to be laid out.  Not always...but sometimes.

I made my EA trem with those same caps (the blue box type) and it worked out well.  The way they are connected to one another in the EA trem allows you to pack them into a nice tight square.  But on other designs they can be a serious nuisance, due to their large size.  And other 1uf film caps are even bigger.  Those little blue boxes are the smallest 1uf film caps I've seen.
