Tools, Tones and Toys for Guitarists
Here’s another alternative to the 3PDT for bypass wiring. It’s based on the method VooDoo Lab uses for bypass and uses a optocoupler to achieve true bypass using a DPDT. I’ve drawn up 2 different layouts for this: a standard perf/PCB layout, as well as another PCB I did in Eagle with the footswitch board … Read more
Got a request for a Baxandall tone stack daughter board, (much like the Big Muff Tone Stack daughter board) and thought it was a great idea as it’s a great tone control. The schematic for this came from this article, which is worth the read. I’ve laid it out two ways, one with board mounted … Read more
Got a request for this one, designed by Daniel Schwartz. Seems to be a pretty versatile cabinet simulator. Might be handy to throw this in the same box as the Mini Amp from earlier this week. More info, schematic, etc here on DIYSB. Also the next episode of the DIYLC tutorial is up on YouTube. Forgot … Read more
Here’s a nice little solid state amp for headphone use or a small 4Ω speaker. Good candidate for a bench top amp for testing purposes. You can board mount the pot and it will fit in a 1590A just fine.
There are a lot of circuits (a lot) that use J201/2N5457 JFETs. Sadly, these components in the TO-92 package are out of production, and many of those that can be found online are either barely within spec or completely out of spec. So I thought it would be good to have a conversion board to … Read more
Came across this design in researching a different project and thought I’d draw it up. It uses 3 transistors and doesn’t take up a lot of space, so you should be able to fit it in a 1590A or add it to another pedal. More info can be found here. Sounds like you can use … Read more
Got several requests for this one. Basically, it’s small preamp to plug into a mobile device for use with apps like iRig. Pretty simple circuit. Shouldn’t be hard to fit in a 1590a or even smaller since you don’t need to include a footswitch.
Had a few requests for adding a Big Muff tone stack to a few existing layouts. Call me lazy, but it’s easier to draw this up than make a whole bunch of random alternate layouts. 😁 Anyway, it should be pretty handy. I’ve included a layout for just the tone stack, and one for the … Read more
Here’s a couple test rigs you can use to test effects before boxing them up. They use the same board mounted jacks I used on the “board mounted everything” layouts I did at the beginning of the year. The first one is fairly simple, using a DPDT toggle to switch between the effect and bypass. … Read more
Here is something a bit different and maybe useful! It’s an “effects loop buffer”. There isn’t a schematic for it but you can find the original layout on Ceriatone’s forum here. You can also find all infos on their original manual here. 12/03/17 Layout updated! Moved 220K resistor and link from S to G on … Read more
