I was looking through reverb and saw this first run Lovepedal Vibe listed and it got my gears turning. Anyone out there have a schematic/layout?

Seems to be less components than a Phase 45. I'd be interested if anyone has any further info on this circuit.

MOD1 - by ratioing the first and second stage capacitors of Phase - 10 to 1, it is said that it will produce a univibe effect.

link for the schematic is not working, but it's available via archive, it's the same as above

Thank you for those links.

In the picture of the Lovepedal, I'm only seeing (2) IC's, compared to the P45 that has (4)

EDIT: I was looking that scheatic of mods you posted. That has 4, P45 only has 2 - my bad.

So in theory, the Univibe mod on a Phase 45 is just replacing 2 caps?

Just to confirm, are these the (2) caps I need to replace?

If you like the mod, you can use dpdt switch to change between vibe and phase.

A bit off topic but, what would make a better "vibe", a P45 or P90?

I ordered a quad set of matched 2n5952, should I just make a 90? :hmmm:

I can't give you the answer on that one, but as far as I remember there were videos on youtube, with modded p45/90 and lovepedal vibe. Here's from phase90 vibe mod, search for others and compare which one you like more.

Thanks for that, That’s a great video.

Sorry to keep using layouts, not familiar with phase schematics just yet. What caps would I be swapping on P90?

From what I've saw there are different vibe mods for phase90. Some involve changing 4 caps as Nocentelli suggested with values equal or similar to UniVibe. Some involve three or only two caps. Here is one of them. Only 2 caps are replaced.
Locate C1 and C3, desolder and remove them. C1 = 0.015uF C3 = 0.22uF
C1 should be the first one. I guess C3 is the cap from the third stage. Feel free to try other values for more or less depth. You can also try to change different pair, C1-C4 e.g.

Thank you guys

Quoting another thread:

"15nf, 150nf, 4n7 and 470pf. Apparently the sequence doesn’t matter" - is this true?

I don't think it matters, but if you're keen on accuracy univibe order is 15nf, 220n, 470p then 4n7 (for C1, C2, C3, C4 as labelled on the layout karul posted above).

Cool thanks again for the responses. I’m working on a P45 “vibe” right now. I’ll let you guys know how it goes!

Hey guys,

While looking up prices for the pedal I originally posted, I discovered this may be a “Magic Boy” not the Pickle vibe. Seller painted the enclosure and added 9v jack apparently.

Sorry for any confusion.

(I am considering buying the pedal for purposes of tracing)
