Another one from the collection. It was passed onto me by an ex-work colleague (ex-colleague, as I'm now retired), who says he found it on the internet somewhere. Apparently, it's of Polish origin, and a certain amount of translation had to be done - by means of Google Translate, so I've been told. ...

From Electronics & Music Maker. The original source is at the top of the "Write-Up" tab

Another one for the collection. Details of its origin are at the bottom of the 'Write-Up' tab on the attached Spreadsheet.

[smilie=a_holycrap.gif] OMG, why? It must have taken ages to copy this info in Excel. Please make yourself a favor, and use CAD software to draw schematics. Many are free. Or even simpler, give a direct link: https://worldradiohistory.com/UK/Practical-Electronics/70s/Practical-Electronics-1979-04-S...

From British magazine "Practical Electronics", this looks good, I've got a few other Phaser circuits, and they don't compare to this.

...and the units keep on coming!!! This is from the September 1979 issue of British publication "Practical Electronics". It's different from the published article, as I generally tend to simplify things by leaving out the battery switching circuitry based around the contacts of special jac...

This is a circuit I've had from something I photo-copied 40-odd years ago. Basically, it's a Fuzz unit, but with a few bells & whistles . I've mentioned it in the text, but the circuit uses an LM301, which needs an external capacitor for frequency compensation. I'm fairly sure that this device c...

From "Electronics & Music Maker", this is a unit that selects the order in which multiple stompboxes are connected between the musician and the amplifier. The design came from the October 1981 issue of the magazine. Note that rather the magazine issue being a pdf file, the entire issue...

The attached spreadsheet shows details of a Chorus/Flanger published as per the Thread Title. I can't find a decent Schematic Capture package I can use, as they're too damned complicated! Therefore, I've used a Spreadsheet set up as squared paper. I have omitted the battery and power input circuitry...

I have to say that this surprised me as well! I recently bought 10 x MN3207 for £6.81p (for delay/chorus/echo units) and 50 x BF244B for £13.13p (for a 3-notch Phaser). I did some digging around Amazon, and I found some real bargains, such as 50 x LM13700 for £30.39p, which is less than 61p each. Fa...

Before I divulge some possible useful information, I have to get something off my chest! I define a "Stompbox" as a sound effect unit that is actuated solely by a footswitch, even if it is under a pedal of any size and/or shape. A "Pedal" is a foot control that actuates a pot(ent...

That is a superb collection ppluis! If you go back via the 'parent directory', you'll find more.

Since I retired in early July last year, I've been digging around the 'net, trying to find schematics (circuit diagrams if you're a Brit!) for guitar effect units (Phaser, Wah-wah, Sustain, etc.) and I've come across some beauties! I apologise in advance if they've already been mentioned elsewhere o...
