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...
here is a little circuit that i was messing with the other day. it does a killer boost to a nice overdrive. it is a bit similar to some mic pre circuits out there, so you can kind of tell that it likes to stay clean, but the lack of caps in the signal path allow this to be done very well. if you get oscillation at the highest gain settings, just increase the 100 ohm resistor(R6) a bit to lower the max gain. i believe i used j309s for the FETs, a 2n5210 for the NPN, and a pn2907 for...
Yet another Ep-3 booster ;) But with added control. For details go to Brian's site
I was in need of small vero layout for this one to build into another pedal I'm modifying, so I've made it. Layout is sized for Panasonic Stacked Metal Films, as well as 25v Philips axial, Sanyo radial Os-Con's and 1/2 resistors, as this is the thing I have and like to use. I hope you like it
I recently bought this FY-2 kit from pigeonfx and started soldering all the parts together.
The final step will be soldering the transistors in place but I still got some questions regarding the trannies...
I can't find the 2SC536's over here in Belgium. :( Anyone got some good advice regarding replacements?
Sure would appreciate it, guys!
I have an Op Amp Buffer design that I build as the Coldcraft Micro Buffer. It's loosely based on that of the Klon, and I've had a few fabricated boards made before.
I'm considering doing a larger run and I'm wondering if there's any interest in these to be available. There's many more uses than just pedal buffers. Y Splitters, Buffered Output Volume Pedals, etc. It's endless. My design isn't rocket science, but it does sound good and runs on 9-18v.
This is a cheap and simple circuit that was developed a few years ago for a series of commercial products. Unfortunately, the manufacturer got out of effects just as this was to go to production...

The prototypes of this sounded truly amazing, and the range of control was better than many similar products. This was to be just part of an effects system - the output of this module would (for example) feed a three-band tone control.
I was wondering what a circuit would look like if that circuit were to an AC or RC Boost what the Eternity is to a Tubescreamer.
This is what came out of that line of thought.
In the schematic, if the AC and RC use different values, the AC ones are listed first. Note that the AC also jumpers D3, D4, D5. The IC is originally a JRC 4557, but any dual opamp should work.
I haven't built one yet, but Eagle sees no problems with the layout.
The 2 red lines are jumpers.
The artwork is 600dpi. The...
Hi, guys, let me show you one of my projects. I build this pedal before month ago.
As a start point I use amz mosfet booster, but I improve it a little.
I try different voltages from voltage divider: C3 and C4, including identical values, but in this case with max gain I have symmetrical clipping and I bring back the original values. Due to unsymmetrical clipping this pedal give even harmonics which is better and more musically ;)
Resistor R8 will give the max gain. Smaller resistor - more...
Schemo Taken from Kit Rae website . Kit says it's his favorite muff right now. I was going to use those parts I like. So this was spaced to comfortable use of my big ceramic caps. I wanted to make it as tight as possible, and frankly - I don't think this can be done much more compact... I'm going to use .15 pinch paxolin vero and drawing this I had this type of stripboard in mind, but I think IC friendly vero will do here when using 1/4w CC's and other type of caps. I may move some parts here...
I was told this would be the correct place to put my first attempt at a vero layout. I'm looking for a second pair of eyes to tell me if you spot anything different from the schem, I think you all know the deal. :D The circuit I lay'd out is Dragonfly's Seven Knob Fuzz. Seemed like a good place to start as it's decently easy but more challenging than a simple boost. After I saw geekmcdaddy's completed SKF I just had to have one for myself. He did his on perf which I haven't experimented with...
Just did an improved board for the Foxx Tone Machine. I found that it wasn't too noisy (a common complaint with this circuit) with the parts as shown. The PCB layout works well, with no hint of instability (another common complaint with this pedal).
I've built three of them this weekend, and they all sound great. There are tiny differences between them, which I put down to transistor gains and component tolerances. However, the variation in sound isn't enough to make me start tweaking...

Since we can attach files to posts, I wonder if it might be beneficial for us to have a thread full of attached source files (like eagle CAD files, ExpressPCB files, etc.) so that users can tweak layouts easier to their own tastes. Any thoughts? It would also help I think with confusion on dpi print settings for layouts if we are printing within the appropriate programs instead of having to scale an image. Some file type threads could be:
A friend complained that his old plug-in Orange Squeezer was stolen at a gig. He said he sometimes liked the sound of the Squeezer into the Dan Armstrong Distortion box. As each circuit just needs one op-amp, I thought I'd make best use of a 4558, and build a squeezer on one side and a distorter on the other. I added level pots for both, and bypass switches, so you can bypass everything or use each effect alone or both together.
The attached pictures show the PnP and the layout. You can work...
The circuit is a quick and simple way to use the 7660S to power 18V effects when you only have 9V available. It switches the supply using the ring terminal on the input jack socket of your effect - plugging in a mono jack plug will ground the 10k resistor, and turn the transistor on . I've used this scheme with several old effects that needed pairs of batteries, when they've been powered from 9V multi-output power units.
Okay dear fellas, here's my latest stuff. I become good enough at repairing pedals so I get more stuff coming on my workbench. Last friday someone gave me this unit. Tracing and project files are done, here they are! :D
The schem:

The PCB, done as an almost exact clone (some pads were useless) of the original unit, fitting in a 1590BB.

A must for every hardcore-fuzzer for A/B-comparision and more.
Features:
* one or two true-bypass-loops
* auto-detection of loops in use
* LED-signalling can be prohibited for blind tests
* 0,5 mA current consumption resulting in a battery life of > 250 hours
* DC-jack
Didn´t have time to draw a schematic, therefore here are the guts for tracing:
Here's a vero I did for a silicon fuzzface I built recently: SiFF+_v2.gif
It's essentially a Lovepedal Dragon/BBB etc etc, which is just a fuzzface with an input cap blend. I made the bias trimmer into an external pot, because I wanted to be able to dial in that glitchy, kitchy, misbiased sound occasionally: Here's the original trace of the Lovepedal that Greg_G did (thanks Greg!) -
It's pretty tiny (9x9 holes) and so should easily fit in a 1590A, if you are that way inclined: I stuck it...
For some time i've been thinking... I usually have a boost at the end of my chain of effects.
So why not build a buffer (KLON-impedance buffer) with half of a TL072 and use the other half as a BOOST!!
As it's at the end of the chain, it's a great combo to regain the lost treble and have that crystal clean tone if you want it and a boost for solo's etc. So i got the schematics of the two that i liked and put them on a 3PDT with a toggle to add in the buffer if you want to!
Below is a HUGE image...
I whipped this up yesterday, and Mr. B Tremblay of Runoffgroove.com has reviewed the schematic and layout and given it the thumbs up. :thumbsup
PCB transfer art is at 600dpi. The PCB dimensions are approximately 2.15 x 1.25 . All the necessary files are in the zip archive attached.
Note: the schematic symbol for Q2 should be that of a darlington BJT, but I couldn't find one that worked right in Eagle, so I just used a plain old BJT symbol.
Note 2: Mr Tremblay says that he recently built one...
