Jen - Fuzz & Sustain
- Thaxt
- Breadboard Brother
Talk about one NASTY fuzz - I have been fixating on that (rare) Jen (Elettronica) Fuzz & Sustain that D.A.M.'s forum has shown & discussed.
It seems like a comparator type setup, only one using an unusual chip: the UA757DC automatic gain control shown in the gutshots. The results are mule kicking slamfuzz, tho.
Has anyone fully traced & posted the schematic yet?
I haven't breaded that Octave Up Sickbox yet - the one that makes use of a 4070 chip as a comparator-type squarewaver - but it still sounds to me like the Jen F&S gets the raw, mountaintop-chop fuzz chord award.
I can understand how anyone who has one of these would'nt readily part with it

I'll try to do something with it today
Will you help me to read these values I can't see?

Hi Sinner,
Regarding this image:
Bear in mind that the variable gain IC we seen in this photo is already discontinued. So when the unit were completely traced, there is an extra amount of work to find an actual replacement.
But, what the heck, this can be interesting to do.
The datasheet of this rare chip are on this link: http://www.datasheetarchive.com/UA757DC-datasheet.html
Cheers,
Jose

...anyway, I'm on it.
I would love to see the pict of the trace side to see how it looks under the pots..

My interest has just been piqued, can't wait to see the schematic.....
