Found match pair of transistors, can anyone recommend a fuzz project?

[niftyprose]

Hi guys, total n00b on pedals (if not circuits).

I just turned up a matched pair of germanium transistors, an AC187 and 188. I know these aren't particularly exciting, but they're what I have on the shelf and I'd like to build with them. My thoughts went to the FuzzFace and someone on another forum came up with a Harmonic Percolator.

Would anyone happen to have a fuzz project for which these slightly unusual parts would be well-suited?

TIA, NP

Making a harmonic percolator was good advice, as you have one PNP and one NPN type. You can't make a Fuzz Face with this pair.
