Just finished this Rickenbacker fuzz circuit found on the Transonic amps that the likes of Led Zeppelin and Steppenwolf used as a backline. Wanted to know how it sounded and didn’t have the room or the cash for a Transonic so I did the next best thing by building one. The schematic didn’t specify what the fuzz circuit used for transistors so I used 2N2222A’s since i had a bunch of those on hand needing be used up. Here’s a clip of the fuzz in action. Very ratty! Unfortunately due to the lack of...
I know, if you're going to build a reverb unit, at least build the Fender, ... or just don't use cardboard
...but still, for reference sake and mostly because you could still fall into the trap of paying 15USD for this pdf ... here it is
This is something neither Google nor I have seen before....
Even discofreq is bidding on it:
from the components used (transistor in TO-106 case, blue caps, white coloured 0,5W resistors) and the term Synthesizer I would date it to the early 70´s - neither 50´s nor 60´s.
Seems to be a simple booster (maybe with ge-diode-clipping) and a tone-control.
Better guts or any information about it would be appreciated.
Note their are three incarnations of this exact V816 Distortion Booster plugin
Red Vox version with germanium transistors
Red Vox version with silicon transistors
Silver Thomas Organ version with silicon transistors (schematic in this post)

#153 Distortion Booster - The #153 JMI Vox Distortion Booster fuzz tone was also introduced in the November 1965 JMI Vox price list . The steel case sported a dark red painted finish. The booster utilized a battery...
This unit seems to be related to the Japanese Fuzzie - Crazy Tone , but the circuit is different.
The Crazy Face seems to be a straight up Fuzz Face clone, but in the Fuzzie - Crazy Tone, something else is going on.
Bought a broken Jordan Gig Wah off the bay in hopes of repairing it and hopefully drawing up a schematic for it. As it stands it appears to use a rather odd (and probably one of the first) opamp (an MC1709C reportedly). Will report my findings when I get it on the bench. In the meantime I found the datasheet for said opamp, quite an unusual pinout!
Hey Guys, I need help with an old (Carlsbro branded) Colorsound Wah-Fuzz I have.
The Fuzz circuit sounds really weak, harsh and thin: you have to hit the strings really hard to get it to distort....
I already checked the PCB thousand times, measured the resistors, replaced the electrolytic caps... without any result
Even replacing the transistors didn't make the fuzz sound better... :smashed:
These are the voltages I have at the transistors:
(Battery measures 9,5V)
Q1
C 3,15V
B 1,30V
E...
Figured we had talked enough about the Nu-Fuzz in the Nu-wah thread. Time for a dedicated thread about the Nu-Fuzz. So where did we leave off? Dan N had posted this schem:
We had previously discussed the odd resistor values and speculated that they could possibly be the result of in circuit resistor measurement? Ron Neely you had mentioned that you had talked to the man responsible for busting open his Rosac wafer and making those measurements...
I'd say its safe to say the capacitor...
I've got one of these, would anyone like some photos of the board?
A schematic can be found here (not by me):

Background:
Several years ago I was given a tangle of wires, pots, PCB etc. by a band mate which produced a slightly muffled overdrive sound that I wasn't too impressed with. I built a makeshift enclosure for it and tucked it away in my loft where I completely forgot about it. A few years later I found it and swapped it with a bass playing friend for something...
i purchased a vintage MXR Distortion+, which sounds as it should, but it has a constant noise that is similar to that of a scratchy pot noise, but lower in frequency. It is quite loud and it renders the pedal unusable. Here is a clip of that (sorry for the large file - this is how my camera spits them out)
No matter how the pots are set, i always get this noise. Also turning down guitar volume does not make it go away. There are no electrolytics in the circuit and i do not see...
Hey all, picked up this preamp last week. Came to me with a pretty bad crackle/hiss. Haven't sorted that out yet, but I did up a schematic.
I verified the transistor pinouts and gain with a DCA55.
Diodes are 1N7xx, forward voltage is 0.78V.
Enjoy and feel free to ask questions.
More pics here.
Decided it would be best to start a new thread for this one, so as not to clutter up the thread for the earlier version of this preamp.
There is an unverified schematic of this already floating around the web. There are several differences from my trace, as well as missing values; let's assume that other one is wrong! :lol:
First, the schematic:

I've been building the Maestro FSH project from tonepad during the last couple of days, and i thought i'd share my findings so far:
First off, there's a lot of people rambling on about the circuit being prone to ticking noise from the LFO bleeding through to the audio path, and some even blame it on the layout from tonepad.
I built mine from the latest document version available from tonepad ( Rev.2, 2008: ), and it's noisefree. If the 10K trimmer is not adjusted properly, there's ticking...
