Univibe + Fuzz Face Problems

[Jaicen_solo]

So I have a Univibe built on the GGG board. The vibe is perfect. I built it with RG's unity volume mod, raising the input impedance.

I have a feeling this is why, when I run a Fuzz Face into it, the sound becomes much thinner and fizzier, and quite swishy in the high end.  Does anyone have a solution so that I can retain the vibe tone whilst still running the Fuzz face into it?

If anyone is interested, I solved the problem. I'd grabbed the wrong psu, once I put the correct one on, it was back to Woodstock toanz.
