Turns out my idea was stupid. I misunderstood the null control. I have now sent the leads directly to the pot. One to each outer lug. That makes a good difference.

The level control seems weird. I get really insane sounds if I go past half way on it. It is extremely  interactive with the filter.

I haven't looked at the schematic  but the wiring for the volume seems odd compared to many others. Should it be lug 2 going to output?

"To get the most out of this pedal, you also need to install an offset null control for the 741. This can be done with a 10k linear pot connected to pins 1 and 5, with the wiper to ground. This gives you tons of control over the fuzz sound, and IMHO is more effective than the filter control. In fact, on mine I just leave the filter on full and tune it with the offset null control. Lots of great, gated, sputtery fuzz sounds there!"

hey synsound, sorry to hear the offset null thing is tripping you up. have to say i haven't tried it yet but there are some interesting comments about implementing it in the above thread at fsb. above quoted comment being the one i had in mind for when i do eventually try it. it is quite a mad circuit and works in a very unconventional way, so applyinging logic that works with normal pedals to it may not yeild the same results because it is such a freak at heart.
but the thread is worth reading. also some interesting stuff about it at d*a*m.

re what it should sound like, the yt vid rocket posted is the reason i built it. that is a great demo vid.

it should basically sound like farting on an upside down plastic bucket while pulling faces with your mouth open and flicking your cheek with your finger. am pretty sure that's how the development team at esr pitched it to management back in the day.

i hope you crack it.
