Any hFE reports from a working (Consistent gate function) NPN version? :) I have been looking at this one for quite some time.

honestly, i never really got super consistent results using the gate on with NPN germaniums which is why i very quickly switched back to PNP. it was only one small run where i used those and found a batch of particular NPNs that worked well enough but i wouldn't recommend them if you have the option to use PNP. ymmv of course!

Alright cool. I've been trying to buy one used for a while, almost had one on ILF but the buyer decided to keep it! ;) I play 7 and 8 string guitars a lot now and this fuzz just sounds so good with bass and ERG's so I'm kind of lusting after it again.

I have sacks of PNP germaniums lying around, but most are like 50-80 hfe. Thanks for the advice Hoss.
I also loved that text on one of your boards about adopting a kitty (think that was yours)

hey you can always get one direct! :secret: :thumbsup :lol:
as for the PNPs, give those a shot - should be cool. yeah the kitty adoption was mine. as someone who has 2 cats from SPCAs, i can't recommend pet adoption enough.

Built this using MP38A transistors and I can get a wide variety of tones that sound great!

Just one question: the Gate function sounds like I remember it sounding (an ex-band mate had a TAFM on his board), but engaging it seems to max out the fuzz. Is this normal?

I used a BAT41 and a 1N5819 for the Shottkeys... I'm wondering if that could be the reason...

Appreciate any help offered. Cheers.

as for the gate function - totally normal. it does indeed max out the fuzz.
