May I? Vox in a Box

Thought i'd post this here too in case someone wants to try it out. There's an old development thread on FSB for this AC30 emulation circuit. There are number of schematic versions with slight differences, but the basics are the same for all of them. It is a nice high gainer with some noise content, so i'd suggest using 220µ for the power filter and maybe adding a 100p cap between germanium transistor's base and collector. I built one to see if the layout works and it's good to go.

Moen Fuzz Moo

A great sounding and cheap Big Muff made in China by Moen which I believe is a clone of the now defunct Righteous Tones Sonic Mayhem.  I bought one of these before I got too heavily into DIY and it got plenty of use despite me also having a Skreddy Pink Flesh, so it's definitely a recommended build.  The 100K in the tone stack means that it isn't as scooped as some Muffs which is probably why I get on with it so well.



The PCB:




Info about the original:
Fuzz Moo Analog Fuzz Box Analog Sustained Fuzzy Distortion: Like any other MOEN Effects Pedal, the Fuzz Moo is designed with analog circuitry to ensure full processing and reproduction of the original signal without losing any details through digital sampling or processing. I have been playing with this one and it's pretty meaty with alot of headroom available. Kinda like an very early 70's Fuzz sound, but it is pretty flexible in acheiving different levels of raunch. Note.. when I say it kicks back, I mean it. There is a lot of gain in this box. This pedal will fight you back, but that is why everyone like its. When A/B'd in a studio against the Muff and some other well-known Fuzz boxes.... the Moo stomped all over them!! Very musical and workable Fuzz tones. Not one to pass by !!!





And the schematic using Pawel's drawing as a template, which I traced from my original:

Madbean Bacon Bits

Basic info about a Madbean original:
The BaconBits Booster is a simple op-amp based booster powered off a split rail supply. It can be used as a stand-alone boost to drive the front end of a tube amp or another effect such as an overdrive. The BaconBits utilizes an input buffer which feeds into a negative feedback gain stage. The result is a clean, high headroom boost that adds a lot of “shine” to the guitar at lower boost settings and dynamic, sparkling overdrive at high boost settings.
