Tools, Tones and Toys for Guitarists
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…
Very close to STL Super Tube. Clipping amp and mids boost section are in different order, plus some slight changes to the buffers.
200th Overdrive layout! I seem to be on the streak with Tubescreamers. This one also marks a special moment. In addition to this being 200th OD layout, i finally deciphered the original schematic which is very annoying to read (all 7-series schematics are). This one is also our first layout for the this series of … Read more
This puppy is basically another TS9, but it has clipping and gain options on “mode” switch. Modes are TS9, +, Hot and Turbo. Latter one acts as a diode lift, but adds a lot of gain. The switch is 2P4T rotary. Original unit has 250K dual gang pot for gain, and for some reason it … Read more
Hehee! Couldn’t help myself. It is in reality a TS9 🙂 If you want it 1:1, then use TA75558 and 2SC1815 transistors (mind the pinout!). You could of course build it with JRC4558D and check the output resistors to make it 808.. I still thought we needed at least one more Soundtank to our library. … Read more
Doron! I think you meant this one and not the MSL 😛 To add a few words, the clipping diodes are placed neatly where you can easily take them on the switch and have your way with them. I would probably go with three position two pole switch and have the middle as diode lift, … Read more
Edit 31.7.2016 – There was still one crucial error on the layout, which made the board defunct. Fixed and tweaked a few things around to accomodate the polarity protection etc. *Should* finally be safe to build.
Got the original yesterday and it didn’t disappoint. Soundwise. The box is what you’d expect and the stompswitch is out of order, so no surprise there. Ibanez’s old cheapo high gain distortion that is articulate and powerful without being mushy or too noisy. Well worth a second look. This layout omits the in/out buffers and … Read more
