Tools, Tones and Toys for Guitarists
Next up in the MXR Custom Badass line is the Modified Overdrive—a classic overdrive circuit with modern modifications for improved performance and versatility. For added flexibility, we’ve added a 100HZ cut and boost control that allows for a more focused EQ when cut, or a beefier tone when boosted. The Bump switch engages an alternate … Read more
Yup. Most of you who know me know that i’ve had more than enough trouble with JFET biasing on some fixed drain resistor designs… This one also has the input cap and pulldown resistor at the input. Already verified by me. I found the best gain to be with drains at ~5V, but now you … Read more
Now. This is per the factory schematic, so it should (finally) be ok – don’t go looking for the old defunct layout, as it is gone for good. Transistors are used for buffers, so i swapped the pinouts for your everyday devices. Tone pot is G-tapered 20K in the original, but linear should work fine … Read more
This layout is for the original Overdrive II, not OD-855. The same circuit has been sold as “The Dirt Box” too. More interesting details of the design at Tonemachines blog.
This one seems to be quite rare thing. You can score one for >$200 at ebay. It is Morley’s vision of the MXR Dist+/DOD OD250, with some noticeable changes. Might be worth a build… Picture from Effects database.
Found this floating around the interweb some time ago. It is OD-3, with tone control, buffering and switching components removed. The original design would be crazy big and undoable (at least for me) on vero. So this WGTP’s simplification of schematic supplied by J. Luja more than 10 years ago should suffice. According to DIYSB … Read more
Info about the original: The Animal is our creating of a 1968 Plexi Sound. The Animal is an extremely open and amp like sound that can get you from a stock plexi to a modified plexi with the flick of the snarl switch. The Animal can get very aggressive but it is by no means … Read more
I think we’ve done all the Ibanez Tubescreamers now 😛 This one is a mix between TS10 and TS808 with slightly bigger cap for fatter bass responce. There was an issue with the output buffer’s vref connection, but that’s fixed now…
Very close to STL Super Tube. Clipping amp and mids boost section are in different order, plus some slight changes to the buffers.
