Jensen Copper Foil Paper In Oil Caps

Ive read a bit on these and all the audiophiles claim these are the cream of the crop... A bit on the pricey side though! I was just curious to see if anyones ever heard them in a LP... or other guitar for that matter, and if they were that good? I dont plan on spending that much on caps.... I have a set of .033 and .047 orange drop 715p's on the way that im going to try, ive never messed with the caps so im eager to give them a try... i did a lot of looking around before i got them and chose them for the good review/price ratio... now im just curious about other types and ive never seen much said about the jensens as far as guitar use goes... heres a link to them on fleabay lol

Two .047/630VDC Jensen Copper Foil Paper In Oil Caps! - eBay (item 310020103763 end time Apr-03-08 06:14:15 PDT)

Re: Jensen Copper Foil Paper In Oil Caps

I've used them many a time with much satisfaction. They sound marginally better ( ie warmer more vintagey ) than regular aluminium foils that Jensen manufacture too.
My only complaint is that their true cpacitance varies a bit more than other caps. The best thing is to usea meter and select them according to their real value.

Hope this helps!!

I prefer the Qs but... never thought the Jensens were very thin sounding, especially the copper foil version. I still have one in my G&L bass and I love it.

Actually, in my experince (which is installing Jensen's & Vitamin Q's hundreds of times over the years), I find the Jensen's warmer/'woodier"/fatter than the Vitamin Q's...

Re: Jensen Copper Foil Paper In Oil Caps

really? Like I said I like both and I use both all time so...

I also like SoZos for the tone control in single coil loaded guitars

Re: Jensen Copper Foil Paper In Oil Caps

This thread has been dead for three years, but I suppose now that it's been bumped already I'll chime in and say that I love the Angela Copper Foil PIO caps in LPs. I've A/B'd them in the same guitar as other (tested for equal value) caps with alligator clips while playing. I thought they were very similar to Zoso caps and the RS Super Caps in sound, but the Angelas definitely had just a touch more clarity.

PIO = potato-in-oil cap? Also known as french fry caps?

Thread resurrection.

Finally got around to trying a couple of Jensen copper foil pio caps in my 78 Custom. Very nice. Liking what I am hearing.

Re: Jensen Copper Foil Paper In Oil Caps

I didn't like them. They were muddy compared to the vitamin Q or K-40.
But it all depends on the guitar. I have found that the same PIO caps sound harsh in a fender.

They look like a well constructed cap, but they are too damn big!

Re: Jensen Copper Foil Paper In Oil Caps



Tried them immediately before and after (and later changed out my copper wire for silver coated bus).

- Small audible difference verse russian ky-9
- I would describe it as slightly less congested
- Definitely not something my mic'ing would pickup
- Seemed slightly clearer even at 10s

All that said we could just be talking the differences in tolerances and picking.

In closing...if you have the cash why not. These are some big honkin truck nuts caps though.

Re: Jensen Copper Foil Paper In Oil Caps

I just realized that I have 2 of the Angela Jensen caps, .022 and .015 I think. I also have one of Matt's harnesses with the NOSK40Y Caps of the same values. Any idea what to expect, if anything, with a swap?

Not sure it's in the same way you intended, but this comparison really resonates with me.
