Here's a collection of vero (stripboard) and tagboard guitar and bass effect layouts that we have put together covering many classic and popular effects in growing numbers. Many of these have been posted on freestompboxes.org, so check that site out for great discussions on building your own effect pedals. Enjoy the builds and please also visit us on Facebook and Twitter
Not much info on this. From what I've read from the BJFE forum is that the 3 knob Sparkling Yellow Overdrive was a short BJFE Customshop run that's supposed to have that old school early American tones, think Fender Tweed, Blonde, and Brownface.

"CC Hybrid is one of the first pedals to use one germanium and one silicon transistor in the classic Fuzz Face circuit.
Hybrid is a stand-alone pedal that contains the same Silicon/Germanium
fuzz face circuit as the original Captain Coconut and Captain Coconut2.
To my knowledge, it’s the first example of a commercially available
pedal to use one germanium and one silicon transistor in the classic
Fuzz Face circuit. It combines the warm, dark organic tone of germanium
with the clarity and sustain of silicon. CC Hybrid gives you the best of
Volume - Set the volume you like, compensate for level changes when adjusting the Grit and Fuzz controls.
Fuzz - Controls the amount of gain in the circuit. Typical setting is all the way up, or backed off a little.
- controls bias voltage to the transistors. This lets you go from
smooth to choppy and everything in between. Typical setting is 11:00.
Past the 2:00 setting the sound takes on a restricted, gated quality.
The extreme range of the Grit control is effected by the voltage coming
into the pedal. Above 9Volts, grit stays smooth at the max setting.
Below 9Volts, grit can sound choppy at gated as low as the 1:00 setting.
If you notice this - don’t worry, there’s nothing wrong with the pedal!
Just set it for the sound you like.
- There's a trimmer inside for backing the input level down a little.
Just like having your guitar volume turned down. It’s preset all the way
There are 2 layouts: one with the original trimmer and one with a fixed resistor in its place.
Interesting sounding 8-Bit fuzz, that's not typically my type of pedal that I thought will get some love. Schematic is posted over at DIYSB.
From the source:
is one of the earliest SHOE designs. It began as an oscillating fuzz
and, after intentionally adding elements haphazardly and then adjusting
the circuit so the pedal began to work again, it turned into something
else entirely. The Pixel is a gated fuzz and is commonly used
on bass, though it works quite well on guitar and other instruments.
When used with a guitar on single-note lines, the Pixel is adept at
producing chiptune and analog or 8-bit synthesizer type sounds. It can
resemble the sound of a classic monosynth or game console. This effect
is most pronounced at higher PINCH settings.
By turning up the PINCH knob, you will create a stronger gating
effect. Turn the control down and you will gain more and more sustain
until the pedal ceases to be gated and can move into some slightly more
traditional bass and guitar fuzz tones.
The Pixel is not, however, a pitch tracking effect as many synthesizer
emulators are. As a result, you can move seamlessly into highly
distorted chord playing simply by changing what you play.
Pixel on bass operates quite similarly, but bass notes will tend to
have longer sustain when played through the Pixel. By adjusting the
PINCH knob, you can also move between more open fuzz sounds or staccato
synth-like tones. Because of its popularity with bass players, the
current version of the Pixel features larger capacitor values at all
stages to let your thunderous low end through.
The Pixel also features a Low Pass control which is very useful in
dialing out upper harmonics. You can go from rather nasal to warm and
fat with this control.
There’s also a new feature on the latest version. That is the Easy
Mode/Hard Mode switch. This essentially lets you select from two
different versions of the Pixel circuit. The Hard Mode setting is quite a
bit louder than the Easy Mode setting, so be careful to turn down your
volume before switching!
The Pixel definitely takes a bit of practice to grasp and you will
likely need to adjust your playing style when playing it to achieve the
best sounds. This is OK, though. Some SHOE pedals are intended to
enhance your guitar and your existing playing. The Pixel is, more or
less, a different instrument and you should approach it as such. With
some creativity and the right mindset the experience is quite rewarding
both sonically and creatively. Use this pedal to write new types of
songs and go on new adventures!
Volume (Top Left): Sets the output level of the pedal
Easy Mode/Hard Mode (Toggle Switch): Use
this to select between two different Pixel circuit versions. Hard Mode
is a bit tougher to master (and much louder) but greatly expands the
number of sounds available in the pedal (it’s based on the very first
Pixel). Play with the Pinch and Input Level knobs to get a number of new
synth-like sounds (Pinch all the way left and Input almost all the way
up is a personal favorite). Easy Mode is a bit more forgiving and has a
softer sound that can be tuned into a more traditional fuzz sound at low
Pinch and Input Level settings.
Input Level Adjustment (Top Right): Used
to adjust the level of signals coming into the pedal and can also be
used to “clean up” harsher attacks due to its built in mild low pass.
Low Pass (Bottom Left):
A simple tone control. Use it adjust how much treble is present in your
output signal. This control will never cut your bass frequencies.
Pinch (Bottom Right):
The heart of the pedal’s sound. Turn the pinch knob up for more
staccato and synth-like sounds. Turn it down for longer sustain and less
synth-like fuzz sounds.
Well as usual just finished a round of exams, so it's time to start posting the layouts I did when I was taking study breaks. This time I'm going to space them out so there's not a sudden flood.
First up the 18v Colorsound Power Boost. Same topography as the Colorsound Overdriver, but ran at 18V, and to my ears boarders on a fuzz. I made 4 different layouts, 2 identical to the original (early & late version), and 2 that have an added master volume pot. On the original the pot labeled volume is really more of a gain pot then a true volume pot, so I figured that it would be much more usable to be able to max the gain and control the output level. The original came with BC184L transistors, but you should be able to use any NPN Silicon Transistor.
