Fuzz Central -- Arbiter Fuzz Face. I personally do not think that wiring up PNP transistors (Silicon or Germanium) as negative ground is one of the best ideas. The PNP transistors are simply not meant to function with a negative ground and osciallation and "motorboating" sounds are common results of wiring a Fuzz Face with PNP transistors as such. Here's some more information from R.G. Keen (GEOFEX): While in theory, the negative ground conversion for FF and other PNP circuits ought to work every time, there are a significant number of times where it causes oscillation, motorboating, etc. Sometimes you can clean this up by putting a big freaking capacitor across the power leads, sometimes you also need a low-impedance 0.1µF ceramic, too, and sometimes you need divine intervention. Try it if you want, but be aware that there are conditions and layouts that will not be trouble free if you flip power and ground.
So, in my opinion, I would always leave PNP transistor-equipped circuits as positive ground. On Choosing a Drive Pedal… | Guitar Gear. Awhile back, I posted an article discussing Overdrive vs. Distortion, discussing what I believed were the fundamental differences between the two, but also pointing out that the end result – no matter the source – will be distortion. The only difference between the two being how the signal is clipped to create the distortion sound.
Overdrive pedals normally produce a soft-clipping distortion, whereas distortion and fuzz pedals create a hard-clipping distortion. Here’s a great diagram I found that describes the differences between soft and hard clipping: As you can see from the diagram of the waveform above, soft clipping clips the peaks somewhat, while hard clipping pretty much lops of the peaks leaving a narrow dynamic range.
This article describes clipping quite well. First up is the booster pedal. Next we have overdrive pedals. Then we have distortion and fuzz pedals. So which do you choose? When I want crunch; I mean rock crunch at any volume, I use my EWS Little Brute Drive. Triangle wave generator circuit with cmos inverter IC. This is a very Function Generater project. can be used Triangle and Squarewave Generator.
The main parts are CD40106 popular CMOS IC and a normal transistor is BC547 or NPN type such as : BC549 , 2N3094, 2SC1815, OR an Old number 2SC458 . VR1 For Control frequency Output. S3 to Seclector High = 1kHz-10kHz, Low = 10Hz-100Hz. Voltage supply 3-15V. As you see the circuit in figure 1. For eaxample Function Generator. Square fuzz. Fuzz quest: Surfing the square wave (Mastotron, Oxide, et al.) View topic - Univox Square Wave fuzz. In searching here, I didn't get any hits for "Univox Square Wave" and only one mention of it for "Univox SquareWave" (did I miss something?)
, so: ...finally got around to building this one. The first thing I did was try a bunch of different JFETs. The classic J201 won out. All others gave me a more gated, broken sound. There were 2 problems. Volume problem: To increase volume, I slowly increased the vol pot. Mild Gating Problem: Anytime I see an odd small value from an emitter, bass or collector to a rail, I always suspect it to be very sensitive, and it was...I slowly increased from 0K and hit a perfect spot around 2.6-2.8K. Here's the final with voltages...It's a pretty loud (will feedback at full) fuzz with a good sweep from fat to thin and killer sustain.
. #2 (cheapout version) -------- Volume problem: Well, there's no cheaper way to increase the volume than remove the diodes...and in this circuit, the diodes don't do nearly as much as others...just a bit more fizz. have a blast. Univox Square Wave fuzz build... I finally got around to building this one and I wasn't able to find any build report for years....And that old build also did away with the unique "distortion" control, which I didn't want to do...so here goes... Original: The first thing I did was try a bunch of different JFETs. The classic J201 won out. All others gave me a more gated, broken sound. There were 2 problems. It was way below unity and the fuzz was still mildly gated with too much pick percussion (clickiness) evident.It turned out to much easier fixes than expected. I built two versions: Volume problem:To increase volume, I slowly increased the vol pot. Mild Gating Problem:Anytime I see an odd small value from an emitter, bass or collector to a rail, I always suspect it to be very sensitive, and it was...I slowly increased from 0K and hit a perfect spot around 2.6-2.8K.
Here's the final with voltages...It's a pretty loud (will feedback at full) fuzz with a good sweep from fat to thin and killer sustain. Volume problem: IC 4049 Square wave oscillator generator. See Other projects in : Digitals • Oscillator And: IC 4049, Pulse generator circuits, Square wave oscillator Posted by admin - September 17, 2011 at 12:21 am We can bring the inverter CMOS digital IC is CD4049 Hex Inverting Buffer IC, to design the Square wave oscillator generator circuit diagram or Simple Pulse Generator circuits, to a lot circuit been simplified. The circuit we use a little equipment, just add a resistor and capacitor are the only one,It uses less energy.
The output frequency is relatively constant, the rate of change in frequency of the power supply voltage is less. The pulse generators can also produce a 50% duty cycle square wave. The ICs in the circuit number CD4069,TC4069,LM4069. The frequency determined by R1 and C1 is F = 1 / (1.39xRxC).
