not going to make FX-X but not planning to give up on this...

i had this idea with the 4007 but didn't have the time...

i would use the mosfets in the chip to have a lot of fairly clean power to hit a rangemaster-ish germanium stage from light overdrive to trebly eighties metal sounds. in between the two stages would be a gain knob and the rangemasterthingy would also have a boost knob of its own. the Ge section would also have 2 parallel input caps (.oo1 and 2,2 uF) iwth a panpot in front and a dpdt to replace the panpot with 2 optocouplers modulated by an astable multivibrator so instead of a set tonec control it would be some sort of auto-tone. the multivibrator would also be made of the 4007.

i had the Ge section drawn out but was a bit puzzled trying to find out how to use the p-channel and n-channel mosfets in the 4007 since they are connected in push pull pairs and i'm not familiar with that. the mosfet gainstage would be a gainstage close to the obsidian but with a push pull pair. and if it's possible to use just one push pull pair to make an astable multivibrator i would have one pair left for another gainstage.
so any ideas? i want to keep this as simple as possible (small part count) so if the multivibrator can be made of the 4007 that would be great.

as a side-note: wouldn't this chip be a good idea to make an obsidian? or several AMZ mosfetboosters?

Only one pair of FETs in the 4007 is hard-wired as a push-pull pair, because of pin count limitations. 2 pMOS and 2 nMOS FETs are independent.

I had an idea for using the 4007 for this month's challenge - but had no time to pursue it.

i understand, but the others also have the gate conected in pairs
