Tools, Tones and Toys for Guitarists
Here’s a fairly unique OD from the mid-nineties and the Polish pedal manufacture Exar Electronix. It’s a soft clipping drive based around a simple discrete opamp topography. Originals have J113 JFETs, but others should work just fine. More info on FSB.
Next up from Vitalii’s traces is Moon Metal from later Exar series. Youtube demo found isn’t all that great, but there’s very nice EQ section and gain range seems quite good as well. Not a small circuit, but i think this could be quite usable.
Another one from Vitalii’s traces. This one seems quite nice modern metal distortion with reasonable frequency characteristics. Should be enough gain too. The 47K at the top (horizontal one) may be a point to tweak for even more over the top gain. Like so many of these pedals of Polish origin, this one seems to … Read more
VitaliiBobrov is doing an amazing job in tracing Exar pedals. This Polish brand has some decent tones and lots of room for tweaking and trying things out. Once again, try to tweak the values at the inverting input to ground. And try on a different pair of diodes for clippers, etc. No demos around for … Read more
Hi yall. Noticed a week or so back that it’s been exactly ten years since my first post here. To celebrate the occasion, i thought i’d post something. There’s been a number of slower years along the way, but so it goes. Life has it’s ups and downs. To quote one of the more interesting … Read more
Recently traced at FSB by VitaliiBobrov, i find this very interesting. Discrete opamp overdrive, that leaves a lot of room for tweaking and modding. Sounds pretty great even as it is. There are never too many discrete opamp designs… /edit – There was an error on the gain pot label. That’s now fixed. Also, the … Read more
