Looking at a vintage guitar effects pedal and trying to find out what this component is. Thanks!

On the board it can be seen here.

How many pins has it got?

 

Could be some kind of tube?

 

0.5uF 70V electrolytic capacitor?

 

What's the other side of the board look like?

 

Has 2 pins
Here is back of board

I thought cap as well but can not find anything like it

 

Un solder it from the board and ohm it.

 

You won't likely find one and you won't likely need (want) an exact replacement. On the other hand, looking for someone else's exact sound can be difficult - chuck berry poke holes in his speakers with a screwdriver to get some unique sounds. Good luck.

 

Probably a cap since it has positive and negative markings.

 

My guess would be that it is a capacitor as well, 0.5uF 70V. Best way to know for sure is test it with a capacitance meter.

 

Iron warming up
Meter found
Post results in a few

 

I believe its Bakelite capacitor.

 

@ISB123 , I think you hit the nail on the head!

 

ISB 123 has the winner is seems

 

So any .5uf polarized cap will do then

Thanks everyone!!

 

Probably since those aren't produced anymore.

 

So any .5uf polarized cap will do then

Provided it is also rated for 70V or higher, yes.

 

Non-polarized might be better for this application.

 

Thats a very early version of an ElectroHarmonix Electric Mistress flanger pedal. The part you show is a .5 uF electrolytic cap.
