BUILD THE FUZZRITE.......

[brian wenz]

.....so I can get some other opinions.....
Hello Hello-
           Threw together a Mosrite Fuzzrite today using 2SB175 trannys.
I built a silicon version about 2 years ago and always wondered  how much difference there would be.  Well, I should have built the germ version 2 years ago 'cus this thing is one nasty fuzz.  I had to spend some time biasing the trannys but after that was done it turned into a fire-breather.  
 I won't know if it's a keeper 'til I test it through the stage rig, but so far I like it.  I'd be interested to know if anybody uses any different germ trannys 'cus the 2SB's are a little noisey [hissy] but they sound great.
Brian.

welll.....errmmmmm...I guess everybody's gone for the weekend???

I want to build it but i dont have any of the Ge trans yet. Im getting ready to build the hot silicon.v

Hello Hello----
   Brent--  Yeah, that was one of the versions I built a couple of years ago.  I actually used 10K res. in my germ version, too...it biased the trannys alot better.
  Jimbob-- I like the Hot Silicon quite a bit...good tone and gobs of gain.

Hello Hello--
    anybody else out there???

i have an orignal 60's one right now that i am repairing the switch on.. this particular unit sounds a little gatey, and misbiased when the note decays..
the fuzz tone is pretty raunch! i like it.. lemme know if you want any pics of the board/circuit..

Hello Hello Ryan--
      Abso-friggin'-lutely I want pictures!!!  Is it si or germ??
I tried my germ Fuzzrite with the band tonight and I think it's a keeper.
Thanks for the offer of pics!
Brian.

Hello Brian, I got some Germ's, Shoot me a Schematic, I'll build one,
Johnny

hello Lonestar--
    Go to Fuzz Central....nice, simple schematic and layout.  Be prepared to adjust the 470K res. that go between the 9v and the trannys for good bias.  I lowered mine  down to about 10 - 15 K .

So Nightingale...since you've had it open there...
 What transistors do you see in that Original?
 Pics yes I'd like to see pics of vintage stuff, since I don't have any here, and I've never seen a Mosrite Fuzzbox...
 I played for a while on a Mosrite Guitar...'fine' [as in minimally small profile] fretted instrument, close Razor Action...unusual looking though.

brian and pete~
MY APPOLOGIES GUYS!! i misread the thread title.. i have a vintage FZ1-A i am repairing the switch on.. sorry to mislead any hopes of a look at the mysterious FUZZRITE.. i will still post the pics of it when i get home.. it is intersting looking.. the circuit is on fishpaper eyelet board, with strands of cloth covered wire here and there..
my bad!

[petemoore]

I like to see the insides of any old stuff anytime! Thanks...

Is this the one to try? I tried some before but never could get the "Rite" fuzz [or anything] out of it... :shock:

[b_rogers]

petemoore,

i think i breadboarded that one and it didnt sound bad but nothing special...

i did use rat shack trannies tho so maybe some Ge's might sound better.

What are your pin voltages Brian?

[petemoore]

Brian, if you're still watching, can you indicate which schematic you used for the FuzzRite?

[brian wenz]

Hello Pete--
   Just got back....
   I used the Fuzz Central schematic.  I had to lower both of the 470K res. that go between each tranny and 9v  in order to get the germ trannys to bias up.  [Somewhere around 10K to 15K seems to work].
  Phoras-- I'll post the pin voltages as soon as I can!  [maybe later today or tonight].  Sorry for the delay!
Brian.

Cool N/P...hope you had a good trip!!!
 Yupp I'll probly 20k trimpot [or so] on the collectors...thanks!
