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
"Pigtronix FAT Drive takes a futuristic analog approach to create complex
crunch tones using CMOS clipping and a variable low pass filter for tone
shaping. Bringing the tone control all the way clockwise takes this
filter completely out of the circuit for total transparency and robust
low end. Rolling the tone control back smooths out the highs, leaving
ample mid-range bloom and bottom end punch.
A Hi / Lo toggle switch brings additional versatility to the FAT
Drive’s wide-ranging palette of overdrive tones, altering the gain
structure for enhanced crunch and soaring leads. The FAT Drive features
true bypass switching and runs fine on standard 9-volt power but ships
with an 18-volt adapter for superior headroom, clarity and overall
Schematic available here.
I've heard that in 1991 former Lell engineer went on to form a new company called Rostex. At least that's the rumor and i have no other information about the brand or the pedal. You know anything about these (or have a demo clip/video), please do post it in the comment section.
For the layout, in addition to adding series polarity protection and input pulldown, i subbed the output buffer FET to common 2N7000 pinout.
And the 3-knobbed version:
(Edit 25.5.2018 23:31: fixed a fault with low wiring and added the 3-knob layout Edit 29.5.2018 20:35: Fixed 3-knob layout that had a misplaced cut on board image)
The SOLO is the newest member of the Pro Co family of stomp boxes. Although it is housed in the same indestructible and road worthy steel enclosure that has come to be a trademark of Pro Co stomp boxes, the SOLO marks a departure from the RAT series of pedals in more ways than just the new cosmetics. With its enormous range of tones, 3 way selectable “hot, melt, & burn” modes, and highly interactive “scoop” and “tone” controls, the SOLO just might be the most versatile pedal in your arsenal.
Don’t let the name fool you, the 100% analog SOLO is no one trick pony. It is equally at ease in both lead and rhythm capacities, and with a wide variety of amplifiers and guitars. Capable of going from vibey, chewy, warm low gain tones, to deliciously mean and crushing high gain tones, the Solo still remains remarkably true to the sound that matters most: The sound of you and your guitar. And speaking of staying true to the sound of your guitar, true-bypass switching ensures that when the pedal is off, there is no coloration of your sound.
Even in its highest gain settings, the SOLO remains extremely tube-like, articulate and touch sensitive. Complex chords ring out with clarity, leads sustain with ease. Roll back your volume knob and it cleans up, just like a good tube amp would. The solo uses three pairs of carefully matched (or should we say, carefully mismatched) clipping diodes to produce asymmetrical clipping. The three pairs are accessible via the “hot, melt, burn” slider switch. This has the effect of making the SOLO clip very much like a tube amp going into natural power tube distortion.
You'll notice there's plenty of room to add 3 more clipping options if you want to use a 6 position rotary switch.
BuGG from Pedalpcb.com has created an EZ FV-1 module for vero layouts.
It is available here: http://www.pedalpcb.com/product/ezfv1.
This is what he wrote about this circuit in our Forum / Requests section (schematic available there):
"This is a fairly straightforward single-algorithm FV-1 circuit, it would
be a nice starting point for learning how to work with the FV-1. For easy stripboard building the PedalPCB EZ FV-1 module is
available, a through-hole FV-1 module for stripboard/breadboard layouts.
(ready to use, no SMD soldering required) The pin spacing is standard 0.1" x 0.6" so it can be handled like a standard PDIP-28 (WIDE) IC. The 24LC23A must be loaded with an algorithm in bank 0, although
multiple switchable programs are possible by pulling pins 16, 17, and 18
high (corresponding to the binary encoded bank number). The internal algorithms can also be used by grounding pin 13. There will be pre-programmed EEPROMs available soon for those who just want
to build the thing and not fool around with programming as well."
"The Steel String Clean Drive faithfully recreates the tonality and feel
of the iconic Dumble Steel String Singer amplifier in a stompbox format.
Designed alongside a real Steel String Singer (#001), this 100% analog
tone tool will do it all from Overdrive, to Fat Boost, to Compression,
to EQ shaping and more. Get the unmistakable Crystal-Clear Overdrive
and Fat Clean Tones from albums like "Texas Flood", "Venus Isle", and
"Continuum" through any clean amp platform"
You can find Bugg's PCB and schematic here.
Spotted this over at General Guitar Gadgets and thought it sounded nice. It's a modified
big muff that supposed to be tuned for bass, and from the clip it sounds pretty nice, but then again how can you go wrong with anything with big muff origins.
Bajaman's overdrive/distortion circuit based on the Mesa Dual Rectifier high gain channel with switchable tone stack.
Original thread and schematic available on the FSB forum here.
The layout should fit in a 1590B box.
Bajaman's overdrive/distortion circuit based on a modified Boss DS-1 with an active high and low tone control section.
Original thread and schematic available on the FSB forum here.
The layout should fit in a 1590B box.
This is based on a Marshall JVM410.
You can find Bajaman's original thread and schematic on the FSB forum here.
There are two versions:
First one with just one toggle switch to select between Cruch, OD1 and OD2.
The second one uses separate footswitches, Gains and Levels.
You need to add an extra pole for LEDs.
Can use any small signal N channel JFet for the buffers (mind the pinout).
What can I say about the Laney Supergroup. The supergroup was based on the same Fender Bassman architecture just
like the Marshall JCM800, Sunn Model T, Mesa Dual Rectifier, and a whole host of other
legendary Rock, Hard Rock, and Metal amplifiers. One of the best descriptions I've ever heard of the Supergroup is that it's like a Marshall JCM800 with more balls and gain. It's just an all around badass heavy amp. And for all my lovers of tall things heavy it was used by the legendary Tony Iommi for years, and Laney even went through the trouble of recreating it to reissue it as a special signature amp for Iommi.
"Taxi Drive is the
Brunetti booster/overdrive. It is endowed with “FET-DIODE” hybrid
technology, class A gain structure, to shape the sound in an original
and innovative way. These features make Taxi Drive very
versatile: you can use it as a simple booster or to obtain a very warm
and winding crunch sound, moving easily from bluesy to tweed shades.
Thanks to sensitive and very effective controls, you can mould and color
the sound as much as you like, respecting the basic and typical
qualities of your instrument. Taxi Drive is perfect to boost crunch sounds into lead field or as a stand-alone effect, it gives excellent results in every situation!"
Original FSB thread and schematic available here.
"A boutique pedal homage to the unique onboard overdrive circuit in
vintage solid state Vox Conqueror amps that George Harrison used on the
White Album and other Beatles recordings. The White Pedal has four
knobs that control volume (overdrive), gain (fuzz), treble cut, and a
bass cut knob that acts as a mid-boost, while a fifth knob (the Yoko
knob) selects the midrange frequency to boost for a parked wah sound"
Original FSB thread and schematic available here. Schematic should be correct but it's not verified yet.
"The Friedman Buxom Boost may be the most powerful tonal solution you
ever put on your pedalboard. Like its namesake amp head, this pedal
pushes a pure, clean signal to conjure the absolute most from your tone.
Turning the boost control is your ticket to volume increase, pushing
the front of your amp for thick harmonic overdrive, or balancing between
two guitars with varying output. Whether you're after a tone tailored
by its active mid, treble, and bass controls or the pedal's ability to
achieve total transparency - thanks to its onboard EQ Bypass switch -
it's all in there. We've even added a useful tight control for reigning
in your tube amp's bottom end when boosted. As expected, every Buxom
Boost pedal is crafted with the attention to detail and fine ear for
tone that comes with Dave Friedman's name. Your tone, just more of it. Just like the Friedman
Buxom Betty amp head, the Buxom Boost sings with a completely clean tone
that makes every nuance of your performance shine though. Simply flip
the pedal's onboard EQ Bypass switch and you have a completely
transparent signal, adding muscle to your guitar without ever changing
its fundamental character. Tuned for your rig. Though the Buxom Boost can be
tonally invisible, its active 3-band EQ and powerful Tight control
enables it to be anything but. With a stomp of a switch, you're able to
balance the voice and output of two different guitars or push certain
frequencies for a solo tone that cuts. With the Buxom Boost's
high-quality components, you'll be astounded at how well it works for
fine tuning your acoustic-electric guitar's plugged-in voice."
Schematic from Bugg available here.
There are 2 layouts (circuit runs at +/-9V).
The first one with the original bipolar voltage converter.
The second one without it.
You must then add the original or a regular one (not sure of the noise difference)
Since I just poster the original Vox Distortion Booster, I figured I'd post the second version while i was at it. Just like the V8161 the V2 is also a Fuzz Face
variant. The Vox
Distortion Booster V2 is similarly as rare as the V8161, but being a
Fuzz Face variant I'm sure we all have an idea of how it will sound.
First layout of the new year!! Figured we'd start off right with
another classic fuzz. The original Vox Distortion Booster is a Fuzz Face
variant unlike the reissue, which there's a layout posted. The Vox
Distortion Booster V8161 is stupid rare, so no video clips, but being a
Fuzz Face variant I'm sure we all have an idea of how it will sound. The Distortion Booster V8161 was made to be plugged directly into your guitar, similar to other effects of the time period.
