There are two dual opamps, and one half of the other is completely unused in the original. So i used the remaining half as a buffer for the reference voltage. D1 and D2 are your clipping diodes. Should be easy enough to add a third switch to act as a diode clipping switch.
Request. This layout adds a Timmy type bass control to the TS808 (but with the lugs swapped round so bass increases as you turn clockwise) . I could have just added this to the existing TS808 post but think it’s worth separating them to show two distinct build options. I managed to shift things around … Read more
No way we’re going to beat last year’s number of layout posts 🙂 We might break the verified 600 before new years though 🙂 Since i was up for taking on the big fuzzes.. Here’s another vintage fuzz with up octave overtones. The layout turned pretty neat with some symmetry in there, but it’ll once … Read more
As requested. I happen to have an original unit in metal enclosure, and to my ears this is definitely one of the greatest Ibanez overdrives. This layout is with your standard transistor pinout and with input buffer omitted. Reason for omitting the buffer is quite obvious… It is big, but should fit in B-box without … Read more
There you go John. We’ll never have enough bass designs… This one is basically a Rat for bass. Thanks to John, this one is now verified. Which also means that the LM7 and FC10 should be safe to build.
Ok. As the original layout for this circuit was originally drawn from a bad schematic and altered later, i thought it would be a good idea to redraw this from a trusted (Dirk Hendrik’s) schematic with original buffering in tact. I also removed the old one from the archives… As this Rat adaptation shares the … 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.
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…
