The ♚741 device is a general-purpose operational. The LM741 series are general purpose operational amplifi- ers which feature improvedħ41 Op Amp Circuit Diagram Explain in detail block diagram of op amp ic 741 with there stages. Although most up-to-date designs beat it for speed, low noise, etc, it still works well as a general purpose device.ĭelivered from pin SNS. Or maybe a "better" opamp would be an improvement.The 741 is the godfather of all operational amplifiers (amplifiers on a chip). From what I gather 741s are kinda trashy sounding by nature, but maybe that's the charm of this circuit. I have mostly duals (ie 4558) available so obviously different pinout. I'm wondering if it would be worth the trouble to try different opamps. Maybe it's based on something else, I don't know. I'm wondering if anybody else has messed with this circuit. I guess I could add a voltage divider before the volume pot if I want to tame the volume some on mine. I don't know how the overall volume compares to the original because that is set internally with the trimmer, and I don't want to mess with that setting since it's not my pedal. I put an 18k resistor in parallel with it to make 10k, but I ended up pulling the 18k for more fuzz range. For the fuzz control I used a 25k pot because I had it handy with wires on it already. I just copied the top part of the schematic, with a 100k pot for a volume control instead of a trimmer. So my clone works fine, and sounds pretty much like the original. Here's a not-so-great copy of the schematic:Ī slightly better. I had an LM741 handy so I built a clone on the breadboard. Sounds really cool going into my Dynacomp. Quite different from a BMP or FF, more midrangey and can do overdrive pretty well. Well I agree that the fuzz is indeed pretty cool. Easy repair, just a loose wire, actually never soldered to the PCB at the factory back in 1991. He said the fuzz was cool, but had quit working. So I was fixing a Morley BFW Fuzz/Wah for a friend of mine.
