Original Tracer Layouts A collection of original layouts for vintage guitar effects. If you want to build real replica's of vintage pedals, this is the forum you want to look at.
This page tries to keep the available projects indexed.
If you want to share files to build a effect that's not yet (widely) available, it would be a pleasure for us to host it here.
The projects should be verified , though, and at least contain a schematic , some layout file (transfer, vero, perf) and a component layout file .
Incomplete or unverified projects will be moved to the Projects in Progress folder: if you fall upon such a project, please report the...
I designed a PCB for this and had these boards fabbed at PCBWay.com. I’m going to add this their shared service as soon as I finish a build page on my site.
Have a bunch of old mullard branded oc200, oc202, and oc206 transistors but they don’t sound great with a stock fuzz face circuit. I tried reducing the 100k resistor which helped some but introduced a high squeal when the volumes cranked. I tried a resistor jumper from collector from q1 to its base but wasn’t a fan of the sound. Any other suggestions? I’m using 6.8k to bias the collector of q2. Much thanks!

I know, the amount of literature and the number of circuits are vast,
I'm aware of Bajaman's work, for example, with lots of amazing amp and cab simulation circuits -- analogue modelling, so to speak :)
and I'm aware of the amp emulation circuits collected and laid out on vero board at tagboardeffects / blogspot:
but I'd like to get a clear recipe for someone who just wants to
get her/himself a guitar and a pedal, and get on playing... knowing that her/his room, apartment is not...

Hello everyone. I'm a fan of the sound of the popular Darkglass pedals, and about a year ago I engaged into making the Fairglass , my first re-adaptation of the VMT and B3K circuits. The Fairglass is still a great sounding pedal and I can't really pick favorites between it and these ones, but the noise could be better even if it's acceptable, and I think I can be more accurate too, while preserving the original goal of making the circuit more compact without compromises. The real...
download and keep a copy, it can be really really handy if you need to do a repair on something
that uses an unknown tank... also demystifies how to tell what a tank is, how to use it, order replacements, decipher code stamps, etc etc
posted this in another thread recently, appeared to be ignored which is fine, but its a useful tool to add to your archive.
peace

Hi everyone.
I'm quite experienced on building mainly guitar pedals and amps and now I would like to try my luck to the studio (semi) parametric eq and compressor world, for personal use. To start with I wouldn't like to try something expensive and very complicated.
So something like a good 3- 4 band (from around 100 to around 15k) parametric eq design with hi and lo pass filters (and maybe Q settings) is good enough for me. As far as compression goes I have...
I created this project while messing around with the ES56033 chip that I used in my Stalker Double Tracker project. I figured out a way to get some modulation, but the chip seems to have an internal compensation circuit, which means you can't control delay time the same way you can on PT2399. However, it still results in a fun little project with some weirdness to it. You can get a walk through of the whole circuit along with all the build documents at my little webpage for it: This project is...
I am working on a layout for an AMT SS-11A in Eagle. All SMD/SMT with 3D models. Mostly, I need someone to check my work and help me design a power supply for this thing. I will give whoever mentors me a set of boards for this project as a show of my appreciation.
It's fair to say that I have been on a bit of a quest to come up with a variety of DIY-able reverbs. I did the T60 Reverberator a year and a half ago, the Spare Room and Riptide reverbs were last year, and now, the TBR. It stands for Tiled BathRoom and started life as an Ersatz Verben, but I did a few large changes to it. It's a single PT2399 affair, so it's more like a slapback with fixed feedback and delay time, but it gives the impression of playing in a super reverberant environment. The...
Hello guys I'm looking for a schematic for the oscillating part of a tremolo optical with 2 important features
1 I need to be able to adjust slow and fast limit
2 I need to be able to feed led on C and E so I have two LEDs pulsating at 180°
I remember a while ago there being a guy who posted an eagle layout for the all famous sansamp bass driver di however, the link he posted has since died as well as his account being long inactive. On the offchance that someone here has it, could you pm me? Thanks!
Here's my latest creation, that Overdrive! No, not that one, this one! :D
You might know I like to be very straightforward or to clean up other designs usually, this began as a test to see if I could be more flamboyant with my designs. Also I wanted to take on the difficult challenge of making an overdrive pedal which doesn't borrow heavily from known designs. In the end my minimalist approach is still there, and this isn't a physically big circuit and the values are all common: despite...

Hi friends
Inspired by Dirk Hendrik's Real Tube Screamer pedal project elsewhere in this section, and after reverse engineering the B K Butler Tube Driver, and noting some similarities, i have designed a brand new design for a REAL tube drive pedal, housed in a Hammond (or equivalent NSC) 1590BB case. There are three circuit boards - a mother board that holds the footswitch, input, output and AC power supply sockets; a small...
Here's a fuzz I put together, its actually parts from other fuzzes that I like.
A cobbled together pedal and based on a Simple boost and a Woolly Mammoth.
It sounds big muff-esque, its a cool fuzz and an easy project for a first PCB layout for other noobs.
If you build it let me know what you think.
Edit: I’ve updated the files. Slightly different than the original as I removed the tone stack.(2020)
Based on that famous Californian amplifier designer's overdrive special #124 with the 1988 skyline EQ mods fitted - the Baja Humble Overdrive Special in 9v pedal friendly format - not built or fine tuned or verified yet as I am waiting on some enclosures. I will probably use a 1590 BB enclosure for this one with two footswitches. I may also tweak the gain structure once I have built it so expect some revised schematic and layout possibly later in this thread. In the meantime, here are the...
I was wondering, does anyone have a schematic for the basic circuit EMG uses in their active pickups? It looks like it would be a hard trace since it's totally encapsulated in epoxy, but maybe someone has a factory scheme?
I've been looking at their website, and it seems like they give enough basic info to be able to reverse engineer a workalike. I'm gonna start messing with it this weekend. I have this idea for a project I want to do about DIY EMG-ing a passive pickup to work like an EMG. I...
welcome to the dungeon. this started as a joke... literally a simple boost thrown together as bits n pieces floating around on my bench. sounds nice with old japanese germs, like 2SA and 2SD npns like d30, sa72, etc... but not quite loud enough. the thing likes a bit of leakage i forget what my cheap chinese component tester read, like hfe of 271 with a leakage of 112mv or something. whatever. sounds boss. not sure of which q i ultimately used, as the markings were worn off... looked kinda like...
I got a board for the Mammoth Electronics Bermuda Tremolo as an add on to a part order from Cusack over at Stompboxparts.com.
The build guide is readily available online but it doesn't have the schematic nor was I able to find it searching around.
So, I decided to trace it before make it. I guess this is the correct place for the thread since it was designed as a diy kit.

The board itself has 3 different gnd pads but they all connect so I just used one big ground...
I have completed a new project for this wonderful community. Riptide is a real spring reverb utilizing a blue Accutronics tank. The circuit is actually rather straightforward, but I haven't seen any fully documented DIY projects for one, so I figured I would make one. The decay time is something in the 2.3-2.4 second ballpark, if I remember correctly. The tank is cheaper than a brick or an FV-1 and you can do things like tank splash if you want to. You won't get the massive splashy sounds of a...
MAN what a suck load of suck. weak, anemic, muddy, crummy... no love at all. first one i'd built, really unimpressed. used a nice vero-fied layout by IvIark over on tagboard. checked all parts, no shorts, no bridges, no bad solder, everything tite.
just a sucky ass circuit that's really quite lame.... and with no balls at all. as far as nards are concerned, strictly innies that should be outies i think... a good 6db or so below unity gain. nobody cared way...
dudes......
wire the input and output of the board to the input and output jacks.break the connection at the c17 r8 node. add a spdt switch.
BOOM!
d'lay suddenly has tails. the thing has enough buffers in it so switching that one connection works mint.
try it and tell me what ya think.
sounds great like this. extra added bonus it's always a buffer on for the end of your chain. couple wiring mods. done.
