check this old fuzz out...

[casey]

looks like all electronics are in one self contained epoxied unit with labled legs!!! 

[casey]

it's called a Rosac Nu - Fuzz

here's a better gut shot:

here's a different one in better shape:

Cool. Is it yours?

There`re a few threads relating to these already. Here`s one.

there are more pics in my gallery

its very "closely related" to the fuzzrite

  I didn't see a transistor.
  Interesting construction technique !
  Does it work ?
  Been there and back a few times it looks like...

its all inside the "packet" - the silicon fuzzrites are this way too - and the fuzz circuits in sanner amps...

My Rosac Malibu 44B bass amp also has this same self contained part.

Yes in there is a two transistor circiut.  I think Sprague made them for Sierra/Rosac.  They also made a wah where some were PCB and some were a similar module.

neanderthal gooping.... 

Haha no way man its THE FIRST IC!!!!!

Checkout the last one, the norbit IC's.  The seem like normal IC's but look at the size.  Inside they had transistors and resistors embedded the epoxy - that's a neadethal IC.

A friend of mine has a rosac wah pedal with a wafer like that also. No inductor...

i think im going to start building something like this....  i just put in an audere preamp in a bass, and it's the same kind of build...  but with the audere, there is a little plastic box expoxied on one side with wires coming out...

 

it even has little trimmers where you can adjust freq. response.  pretty neat.

i guess heat is not a problem?

  Looks like a great solution to having no board, 'a hanging garden in venus flytrap'.
  Plenty of thick-ish wires seem to hold it together, effecient.

i bet you are right...didnt think of that before.  i did that one time with a copper pipe cap and some hot glue...

i have some DIY versions lying around. i use them as add-on's in pedals. i have buffers and tone control circuits. they are made by folding the nessecry components in a way that they are soldered next to each other with the wires coming out on one side. then i put it in the corner of a small plastic bag and put in some hot glue. with the bag you can nicely press it between components and around all of them so everything is encapsuled. when the glue is cold it's easy to take of the plastic bag.

i've done these a more than a year ago and they still have thin wire. right now i use the same stranded wire for my pedals as i use in tube amps. they never break and look better.
