UPDATE: My thanks to reader William Badjek, who found in error on page 31 of the v01 project file, which would have prevented the tone control from working properly. The schematics, however, were correct in v My apologies to anyone who got stuck on this! If your record collection includes a lot of albums from around featuring skinny guys with long hair and flared trousers, you need one of these! It sounds incredible. And unlike strict clones, this version runs on a regular modern power supply like the rest of your pedals.
You can round up all the parts from the usual suppliers for less the 30 bucks, or just order a pre-assembled kit from Mammoth Electronics. View a brief demo video of the final product here. And fill your cranium with everything you need to know about germanium here. Happy soldering! As I said in my email earlier today, Thanks so much for the great projects! This one looks and sounds from the video like a great build.
I have an extra DPDT laying around :what:. One cap goes through the two upper lugs, and the other through the two lower. Diodes, electros, etc? Unless you are a practiced and precise solderer is that a word? I will go with the premise that it is indeed a word. Hello fellow Fiends! Although some may already do this. I plug my guitar straight into my looper and then out from the looper into a circuit on the bread board.
This way I can make a loop and then put down the guitar while I madly go about twisting knobs and popping components in and out of the circuit on the bread board. Well I do hope this makes sense and that some of you may find it a useful technique to apply to your tone bending madness. Thanks again Joe! Only things to add: Make sure the output level is close to what it would be bypassed some loopers have a independent gain stage so you can get an accurate read on the dynamics.
And plug in your guitar once in a while just to get a feel for touch response. Quick question. Particularly with theI need to hit a big chord really hard to get any noise at all our of my amp — it sounds as if I have a very aggressive noise gate ahead of the circuit.

These opamps are two JFET transistors in one package, but with different characteristics, which gives them difference in sound.
We will not go into any details right now, maybe in another post. Considering I was only starting out in the DIY projects, this pedal build was rather hard. After some trial and error, I finally got the schematic working.
I can say, that I had genuine fun while trying to route the PCB. It is always a challenge. The PCB turned out to be almost the same as the Matsumin version, but I was sure that it was right with all the measurements. I will have the picture right down below, but if you want, you can download Sprint Layout files in the end of the post. PCB Components list It is a basic analog scheme, so not so many components can be found in this one.
It is easy to connect all off-board components and position them how you want to in a case.

Article written in Last update January It was designed and built by audio electronics engineer B. Butler Brent Butler. Around Butler designed and began making an early version of the Tube Driver, one of the first tube overdrive pedals. It has evolved over the years and there are many versions a list can be found HERE.
It generates anything from a smooth, light overdrive tone, to a classic rock-style heavy distortion. At high gain, it is very reminiscent of the lead crunch tone of a Marshall JCM amplifier. At low drive it can deliver a Fenderish smooth gain boost or a bluesy overdrive. It is not very versatile sounding through some amps, but exceptionally good with others. It can be difficult dial in a tone setting that hits the sweet spot, and some people find it finicky and hard to get along with due to some design issues, but in the right setup, with the right amp, nothing sounds quite like it.
The TD has a very unique voice that I have never heard another overdrive replicate. The Tube Driver looks like something from the bridge of the Enterprise from the s Star Trek television show.
The 5 knob version adds a MID knob. Inside is a hybrid fuzz - pre amp circuit. The hard clipping part of the distortion comes from the integrated circuit chip, or op-amp. That strong signal is fed into a vaccuum tube, which does not work to amplify the signal as it would in the pre amp stage of a typical amplifier. It filters and colors the sound with the tube characteristics.Klon Centaur/Ceriatone Centura Full Real-time DIY Build. Unintentional ASMR electronics soldering
The circuit only draws about 30mA and the tube is actually only running at 12v, a fraction of what these tubes run in a typical amplifier. This is called a "starved plate" design, and you won't see much tube glow, if any, if you look inside. It would seem that the tube itself would make very little difference to the sound, but it actually is an integral part of the sound, and different tubes or tube types will alter the sound in different ways.Forums New posts Search forums.

Especially with single coils. Big fan of the Hermida Zendrive -based Mahayana Drive. My favorite OD pedal at the end of my pedal chain. Great on its own, or really great after fuzzes or distortions to give a nice thick creamy boost to the dirt. The way I like to use it is with the Tone pretty low around 10 o'clock and the Voice quite high around 3 o'clock - not bright, but still very clear.
And the Drive also quite low - between I built mine on vero, but the PedalPCB layout looks really neat. BurntFingers Active member. If they make a bb preamp board, then that one. If not, then the Timmy.
Or Tommy as they call it. I'm digging the Angry Andy plus. K Pedals Well-known member. Dali said:. Last edited: Dec 19, Denso New member. For me, it's the MDMA. I use two of them! I've tried the Ethos, Paragon, and Tommy, but they didn't stay on my board for long. Barry Well-known member. Of the few I've built the Parthenon and Paragon so far. I already made that one. Quite versatile little unit.With an OverDrive account, you can save your favorite libraries for at-a-glance information about availability.

Later in the sixties, the first distortion effect boxes were made to simulate the sound of razored cones and overdriven amps. Now, most amps have a distortion control, but distortion effects are still popular. When talking about distortion, you can usually hear the words overdrive, distortion, fuzz and crunch. They are words describing the type of distortion an amp or an effect gives out.
Overdrive is a natural and smooth sound, while a distortion is more rough. Fuzz is a metallic and very rough type of distortion that turns the sound of a guitar into a fuzzy sound. Crunch is not a specific type of distortion, but mild overdrive or distortion. Usually distortion effects use solid state circuitry like transistors, opamps and diodes, but there are a few commercial tube overdrive effects available like the Chandler Tube Driver and Matchless Hotbox.
Here are the most common distortion effect types:. Just like overdriving tubes, transistors are being overdriven by setting them to run at the top of the amplification range. This creates nasty, distorted tone.
Usually fuzzboxes use overdriven transistors.
Printed Circuit Boards
Check out different Fuzz Face -like designs to see what I mean. Different types of transistors distort differently. Silicon transistors make a nasty, metallic sound.
Germanium transistors have a little smoother sound. Germaniums were used in the late sixties on the original Fuzz Face, for example. This is a very common way to create distortion. Two diodes shunt to ground the opposite way around will cut away the peaks of the signal and thus, create distortion. Usually made with silicon diodes. Another very common method. Two diodes are connected on the feedback-path of an opamp or a transistor.
Ibanez TubeScreamer uses this method.

There are also different methods for creating distortion. To mention a few, there are zener diode clipping and CMOS inverters. Both are commonly used for tube-like tones. Opamps or operational amplifiers are probably the most common component in creating distortion. The gain of a non-inverting opamp is set with resistors R1 and R2.
