DEMO Moosapotamus 360 bass fuzz

Moosapotamus 360 Bass Fuzz - perfboard.

I didn't have the time to post a report. Since it came up in a conversation...

I found this circuit by pure luck, exploring Mosapotamus website. He says it's his favorite fuzz, so it got me curious.

It sounds more than very interesting. Obviously it will sound differently on various amps.

I used what I had available (I am a bit out of money these days), so I had to subsitute a few things.

Q1 BC550 = BC549C
Q3 (socketed) 12N1306 ( ge. NPN 60-300 Hfe) = 2N2369A (si. 40-120 Hfe) or 2N3904, 2N4401 (60/100-300). I am open to suggestion on this one. All my germanium transitors are PNP, unfortunatly. I am afraid I am loosing a part of this circuit's character, without a germanium transistor there...
It sounds amazing to my ears, but maybe it could be even better....

Fuzz B500K = A500K

3.3 uF, I soldered together 2.2 +1 uF
2.5nF = 2.2n+250p (green and red caps on last pic)

I wonder if these substitutions are ok, any downside in your opinion ?

I made a demo some time ago for a fellow forumite, interested by the original amp acoustic 360 :

(Can) You Make My Dreams Come True! (?)

When I was young (20 years ago, or so), I got into The Doors. At the time (Sophomore) I thought that I was into some proper adult/mature music. As a result, I became a fan of the tones of Robby Krieger, especially his fuzz tone. For ages I was under the assumption that he used a Maestro...

My first demo, if you are in a hurry you can go directly at 2:40'...

Go on souncloud and read the description for more information about what's happening in this audio test :

Really nice! I remember seeing your post in the other thread many months back and being intrigued. I’ll have to remember now to build this one too!

Excellent build!
I think it's fine to sub out the Ge for Si on most bass circuits, at least to my ears, I often prefer the Si.


This should generate interest in the Wish List.

The 360 is one that should be on offer in the PPCB shop, especially the Moosapotamus version.
Whenever I've tried to get the BYOC PCB, it's sold out ... which is okay because Robert will make this happen!
